[@Black_Sniper2587]

DarkDragonWing i have a p0401 code do you think a bad o2 sensor might be the cause of it?

[@emranali1705]

GJJS hey bro, i see you having the same problem as me, did you change your O2 sensors or the catalytic converter? my mechanic is saying i have to change the catalytic converter and it will cost around $400. i feel they robbing me

[@Black_Sniper2587]

Emran Ali i changed all that but a mechanic told me there may be a clog somewhere in the intake manifold.

[@temkaline]

hi guys i have 2001 MMC lancer 4G15 GDI in my car 2 trouble code is coming p0425 p0325 how i solve this

[@josefranciscoacevessanchez5508]

@@emranali1705 if the change is for a complete exhaust manifold that have one catalytic conveter cartdrige inside, $400 its probably a big deal. If your mechanics just gonna put a new catalytic converter into your manifold it should cost just $200 but i dont know if it is legal into your country

[@cesaralfredotrejo]

I can't believe I saw all these steps in a single 5 minute video. Great job btw!

[@astinasheel]

This video is 8 years old and it has exactly what I needed thanks

[@rafaelfavela77]

Great video, tried the spark plugs, didn't do it, took it to a shop, they gave us the readings, replaced mass air flow sensors and new computer, runs like a champ

[@slvrserfr]

Upstream smooths out acceleration hesitation, downstream smooths out backpressure when decelerating. Noted that when I replaced mine. Good video!

[@JayBuiAJS]

Same problems!!! I replaced just about everythings under the bonnet the car improved alots. The only thing I havn't is the ignitions coil. Ignitions coil replaced the car runs good as gold!!! Thanks for the great video MAC. It's help alot!!!

[@DarkDragonWing]

nice! cheers!

[@user-pi3ep3px9n]

Well done young man ( well u may be old now due to when this vid was made ). Im an older home mechanic and you went through the diagnosis steps very quickly and clearly. Ticking each negative result off as you went, this was very helpful to me and comfirmed component parts I needed to check and possible results. Thanks for the Video work and succinct commentry ; Your still helping people yrs after.

[@usmanakamani]

thanks .... i am having same problem and i have really learned a lot from your video .... keep up the good work

[@pam2147]

It is good to see a young man doing good things. Keep up the studies. Great video.

[@mixytv3258]

My oz is 400k miles an no engine light on It work perfectly

[@DarkDragonWing]

Hi there. 1.Check if you have bad inner & outer tie rods. 2.If you have good or changed inner/outer tie rods and still feel vibration, try doing the alignment or check if your front wheels are good. The main cause of the vibration is the bad wheels/tires. Suggestion: you can try replace your front wheels with rear wheels to see if that will do it. good luck

[@Adrian-mk8nl]

Very helpful video.

[@KIKASS187]

I would say you did the right thing by cleaning the (MAF) Mass air flow sensor,(IAC) Idle air control and also the (O2) Oxygen sensors nice job

[@MattacksRC]

awesome how you extened that wrench but just putting two together.. I would not have thought of that.. nice man! XD

[@HebikiWim]

my 2002 lancer is running better..thanks to your videos that I've referenced. keep up the good work.

[@DarkDragonWing]

+dunpealhunterc I'm glad, cheers!

[@bricetracy1237]

Can you clean the down/up sensors with carb cleaner

[@MarcGyverIt]

Brice Tracy No, do not do that.

[@bricetracy1237]

Already did and it worked amazingly

[@michaelmosher6755]

rebel haha neat

[@DarkDragonWing]

Yea man, I do teach myself working on cars. Cheers

[@Turbo-kv4ey]

Nice video but never redline a car cold!

[@DarkDragonWing]

Jay Young oh no..

[@russelrimmer6313]

DEFINE COLD....... the temp gauge is registering ABOVE the cold line,, and as long as the valves and rings have oil and condensation (if cold outside) is off the cylinder walls, rev it all you want.. But a first start after 8 hours straight to a redline..yeah thats just dumb.....

[@DarkDragonWing]

No problem. Oh, I believe I have showed you in the video how I took it out. I basically cut the wires and use a wrench, the ring wrench with another wrench to kind of give it a torque or a lever. So I can turn it easier. I thought I was gonna bring it to the mechanic, but I figured, I should ruin it before I pay some money. However, I got it out myself.

[@mikekoz68]

Interesting video but.....why would you just start changing/cleaning random things? That is a complete waste of time and you seem way too smart to just do random stuff. Also buying your own "code scanner" seems like it would be well worth the $100 or so seeing how you do all your own work on these cars

[@DarkDragonWing]

+mikekoz68 Oh most of these things are the things that I need to change or clean. At the time I just bought the car, so to make sure that I can trust it and know where it is at, I have to perform all these things. cheers

[@terrysagan]

What had done, an experience not waste of time, important point is by doing all this wastage of time gone into usefulness of time as U tubers get great deal of knowledge

[@zh137dz]

Once again, thanks for these videos! I've been fighting to keep my 2004 ES alive since I've been its only owner.

[@grzegorz16100]

Ever heard of something called diagnosis?

[@corolla9545]

I bet he didn't know that....all he knows is to f*ck the engine until he finds the problem.

[@DarkDragonWing]

I just squeezed it within like 2 seconds... :D I would love to solder it but, this way works too.

[@marcelrosi8313]

To change upstream sensor was easy for me . Downstream sensor for someone who never did it it's little challenging . Downstream sensor it's between driver and passenger side under the car "next to the catalyst converter" . When I was changing both sensors I just cut wire and removed it " so you don't need some special socket ".But to find out where to plug in new one 'downstream sensor :_) O my good > That took me a while to find out , because I didn't want to cut wires on new one . If you take carpet out on passenger side in the left corner close to the shifting gear is plug in .It took me 2 hours to change both sensors , but I'm glad I did it and for next time I can easily do this job in 1 hour .Anyway I have to thanks this guy

[@pfylip]

I have a 2005 ES and the engine light came on 2 hours after I bought the car. Code is P0421, same as yours, but I don't have a rough idle yet. I guess I'll do the same fix you did, thanks for the demo. Your Lancer vids are great, keep it up.

[@DarkDragonWing]

I see. Thanks. I think eventually I will have to change the fuel filter on my car sometime in the future. Cheers

[@DarkDragonWing]

That's good. Yes, it it normal. The RPM at idle will be low when the engine is warmer. Once you change the O2 it will even be better.

[@DarkDragonWing]

You're welcome and thank you! I'll keep posting if anything comes up.

[@benholding3974]

Hi maki I cleaned my catalytic converter out with hot soapy water lol,left it to dry for a day then refitted it there is certainly an improvement with gas flow and horse power

[@DarkDragonWing]

No, only one small piece of plastic there that you have to remove. So that you can lift up the carpet. And the reason why I cut the wires is because I want to fit the wrench ring on the censor. I couldn't take it out with the socket.

[@youngmarioyoung1]

Just wanted you to know that all your videos on the 03 Lancer ES are very helpful for me. I'm about to purchase one and I can't wait to follow your tips & tricks. I wish you did a LED bulb replacement for those in your tail lights

[@DarkDragonWing]

Right on the Right Front-side (passenger side). At the left foot of the passenger. 3:28

[@p0serj0nes]

Your videos are great man. I have a 2003 Lancer and this is the first place I go when I need to work on it. Thank you!

[@DarkDragonWing]

No problem. Glad to hear!

[@DarkDragonWing]

Hi. He was just showing how to disassemble/reassemble the IAC so that you can clean the inside or you can change the parts that need to be changed. . If you don't wanna mess with it, I would say clean it like I did at 2:19 . Or you can buy a cheap non-OEM one on eBay.com for $40, but I don't know if it's any good.

[@DarkDragonWing]

At 3:25 underneath the car. And the plug is under the passenger's left foot (inside the car).

[@DarkDragonWing]

Sorry to hear that, I'll do that as soon as possible.

[@DarkDragonWing]

No, they are different. There is Denso O2 DOWNSTREAM and there is Denso O2 UPSTREAM. . So go find it. Denso is OEM brand for Mitsubishi Lancer O2 sensors. . Go to ebay.com and search for: Denso O2 Oxygen Sensor UPSTREAM Driver Left Side New LH Hand 234-4739 . Cheers

[@DarkDragonWing]

I used socket wrench. Long socket and short wrench.

[@DarkDragonWing]

No, I haven't got the SRS light off yet. . And yes, if they say it fits, it should fit. :)

[@DarkDragonWing]

I'm glad to hear that.

[@DarkDragonWing]

That one looks nice, too.

[@DarkDragonWing]

Yes! If it said so.

[@henrymerino6038]

I like that you know how to do all that kind work you are a very sharp kid thank you

[@DarkDragonWing]

Yea, could also be the EGR too. I have a video on that.

[@DarkDragonWing]

No problem cheers!

[@DarkDragonWing]

Sorry, I have no knowledge in those areas yet. I wish could help. Hope fully you can figure this out by searching for more on google.

[@383hemicuda]

Best produced car fix video I have seen. Thanks.

[@DarkDragonWing]

thanks, cheers

[@DarkDragonWing]

Man I gotta say, I have a crush on the rotary engine. I like both RX7 and RX8. I like the look of the RX7. The new modern type of driving goes to RX8.

[@DarkDragonWing]

Yup. - unstable idling - feel like a flood in the cylinders which gives no power when you try to accelerate it - seems to be fine once it's running for a while - happens every time when you start it up especially when it's cold

[@TheRyder702]

Thank you so much I had a idle problem where it felt like it was running rough and was going to die on me especially when I came to a stop. After veiwing your videoI troubleshot everything in your order and now it runs great thank you for posting and please any other issues I would like to watch your video's on them too. thanks a million....

[@felixbeltran472]

Excellent videos! Keep up the good work! Youre like the cleanest mechanic Ive seen! Lol!

[@DarkDragonWing]

Felix Beltran Thank you! lol

[@felixbeltran472]

I have a quick question since you read your comments! My lancer 2005 Rallyart has a battery drainage. The battery is ok but overnight or in a few hours is totally drain. Any suggestion?

[@DarkDragonWing]

Felix Beltran Get it checked to see if it's the battery that is draining or the alternator that is bad.

[@DarkDragonWing]

No problem. Cheers!

[@DarkDragonWing]

Lancer Fix | EGR P0401 / Engine Light - Ep.6 Try this one if this is what might having trouble with. With the cat, I don't know if I will have a trouble with it any time soon.

[@DarkDragonWing]

Hi, if you can go to Ebay and search, these will be the ones I would buy: NEW DIRECT FIT O2 OXYGEN SENSOR REPLACEMENT - AIR FUEL RATIO PRE CAT UPSTREAM NEW DENSO 4W OXYGEN SENSOR MITSUBISHI VEHICLES VARIOUS First one is the upstream, and the second one is the downstream(it's universal and you'll have to wire it). The part numbers are varied due to different companies that make them. Here is another downstream that you don't have to wire anything: Bosch 15360 Oxygen Sensor Cheers!

[@DarkDragonWing]

Ok I can see how it is. I think you can fix this by checking the EGR (see if there is any tube leaking). Take a look at the video below. Just search for it. I know it's not the same code, but just so you can see to help you figure it out. To help you by making video, that might not be possible for me. Search for photos on google would help too. Lancer Fix | EGR P0401 / Engine Light - Ep.6

[@DarkDragonWing]

no problem!

[@DarkDragonWing]

I like EVO9 too! I will make mine look like one.

[@DarkDragonWing]

I looked on Google images for the location of both sensors. So I think you should do the same, just search for IAC EVO 3 location or IAC EVO 3 replacing. I read people's forums and also watch youtube videos that will sort of help me to see stuff better.

[@DarkDragonWing]

Do one thing at a time. You will get there eventually.

[@DarkDragonWing]

It's a drum loop from MAGIX Music Maker in the category of HipHop Vol. 10 called Combine D.

[@zztt3]

Hey dude, just started working on my 03 es, your videos are helping a lot. Had a similar problem due to cat converter.

[@DarkDragonWing]

cheers

[@DarkDragonWing]

I see. That's good, don't forget to clean the rust check before you use the wrench, so it won't be slippery.

[@DarkDragonWing]

I don't know the specific way for that, but the general ways to reset the car's electric system without a high-tech-code-reader are: 1. Take off one of the battery cable for a couple of minutes. Then put it back. or 2. Take both battery cables off, then touch them together and wait for like a couple of minutes. Then put them back.

[@DarkDragonWing]

So sorry, you would have to wait until it's warmer. It is very cold here in Minnesota(-20F) and my garage doesn't have a heater plus my budget is low. :/ It would be a while, but I'm sure that I will do a video of it.

[@DarkDragonWing]

haha i see. alright, will see if the denso will do it better than the bosch. I'm not sure if it's the bosch, but you gotta try.

[@DarkDragonWing]

yes

[@DarkDragonWing]

Did you unplug the battery before you did all that? If you think everything is good and in place and if you just want it to start it up, what I would do is lose the tube from the air filter to the intake, so that you can see the throttle hole, and spray some gasoline or engine starter spray in there. Not too much though, just enough to get the engine started. Good Luck!

[@DarkDragonWing]

3:24 I believe it is located on the passenger side. (The white connector)

[@DarkDragonWing]

It's almost been a year now, I have not had any problem with universal sensor (that was made specifically for 2003 lancer es) so far.

[@DarkDragonWing]

Yes, but before you do fix that, I would say cleaning the EGR would be something easy to try first: Lancer Fix | Exhaust Gas Recirculation (EGR) P0401 - Ep.6 Cheers!

[@DarkDragonWing]

Glad to hear!

[@POPOAZTEC]

Thanks, I'll try that tomorrow. I have taken the tubing off but I have not tried to spray anything in there. I'll make a video!!!!!

[@bamsgian9759]

We're really thank you for making this video series

[@TheAwesonymous]

putting those two spanners together gives you more "mechanical leverage" it's called. good idea.

[@DarkDragonWing]

***** Could be the Lancer Fix | Exhaust Gas Recirculation (EGR) P0401 - Ep.6 Make sure you changed your o2s to DENSO

[@tererodas1366]

DarkDragonWing k

[@702xRyder]

Dude your pretty good at fixing your lancer I be getting down too on mine but in Vegas

[@nodlehsla]

Dude you are super talented keep it up

[@DarkDragonWing]

You mean the brand of the O2 sensors? The OEM brand for that is Denso.

[@DarkDragonWing]

TY!

[@gustavogas9669]

Kool Video Amigo.... wish others on Utube would keep it simple like this.....

[@DarkDragonWing]

cheers

[@DarkDragonWing]

If none of the things you did to fix it didn't work, I would say putting in O2 Sensors would be something I would do. Or before that, you can clean the EGR if you want: Lancer Fix | Exhaust Gas Recirculation (EGR) P0401 - Ep.6

[@DarkDragonWing]

Here is what I found on eBay Denso sensors for 2003 lancer Upstream 234-4739 Downstream 234-4642

[@DarkDragonWing]

Yes Thanks! I got one obd-II scanner now Cheers!

[@pinkyhotmessx69]

What code did this give you with the rough idle

[@pinkyhotmessx69]

Instead of removing the plug from the bottom why didn't you just cut the wires install then reattach the wires

[@DarkDragonWing]

Good luck!

[@DarkDragonWing]

Yup.

[@DarkDragonWing]

Sorry, I just feel it squeezed down just a little bit, and a little bit tight. I didn't use the torque to measure it.

[@DarkDragonWing]

O2 sensors' rough idle: unstable idling, feel like a flood in the cylinders which gives no power when you try to accelerate it, seems to be fine once it's running for a while, happens every time when you start it up especially when it's cold... I would if the engine light says so. I also would even If the engine light isn't on or doesn't say if it doesn't cost much and I can do it myself. Otherwise, it could be a vacuum leak which I have no experience on that part. Hope that helps!

[@DarkDragonWing]

ty!

[@higgout]

I find all your vids helpful.

[@DarkDragonWing]

Does the Engine light show up?

[@DarkDragonWing]

Right on the Right Front-side (passenger side). At the left foot of the passenger. 3:28 CHeers!

[@DarkDragonWing]

Nice! And just cut those sucker wires off and put a ring wrench on it and torque it with another wrench. :D And um I would suggest you to stay with Denso brand because that's the OEM for Lancer. Cheers!

[@DarkDragonWing]

Nice! no problem

[@DarkDragonWing]

You should change the oxygen sensors and see if that will do it.

[@DarkDragonWing]

I don't know, but you should google image it. Keyword, "fuel filter 2000 mitsubishi diamante location."

[@DarkDragonWing]

There are two fans right? So only one running? Well I guess you should check if that fan is not working. Technically, both fans should stop/or running at the same time. (you should do more research, I can only guess)

[@DarkDragonWing]

1. Try a different wrench, get the fittest one or 2. Use a strong pair of grip pliers ..The last think that I would do is to take it to the mechanic

[@Realistix1]

Thanks a whole lot. I was wondering where the wires.ran to from the downstream sensor. Lol time to pull up the carpet!

[@miner123454321]

hey dragon!!!! thanks for all the tips if you remember me talking about my spark plugs, i finally got the boot out and what do you know!!! oil in the spark plug well!!!!!!!! good thing u made a video of changing the valve cover gasket!!!! thanks!!!!!!!!!!!!!!!!
