[@mister.c4631]

I don’t think there is anyone on KZbin with this much knowledge on BM’s This guy is the BM god

[@MoshiDFA]

PERFECT timing for this video! My catalytic converters are making rattling noise on start up according to my mechanic and I did notice power loss. Thanks for the video

[@isaacb4955]

Michael Moshi did you end up replacing your cat? How did you fix why your cat died in the first place?

[@jonathanzivumbwa4641]

Thank you. I have had this problem for 3 weeks now and there is a sound coming out of the catalytic converter but one mechanic had said I had an engine knock. Glad to have watched this video

[@ricardocamara1362]

Good ,useful advice , great tip, thanks Jason. Cheers Ricardo from Australia ( merc c180 w203 .2000 model)

[@patrickbeverley7105]

Dude, thank you! Clogged cats are not a myth. I've been chasing down a major loss of power on my e36 325i. I ripped off the exhaust and there she was. That midrange BMW torque. I was about to replace the clutch because I thought it could be slipping...

[@smisoian2255]

Did you finally get the desired power on your bmw? I'm sitting with a same problem

[@iAlwaysSpeakTheTruth]

Jason can you make a video on how to replace the vacuum hoses on the M54 engine? My hoses are cracked and want to DIY but they are behind the engine the one that is cracked.

[@Edvinfrankner]

Thanks for this video! I bought my first e36 325i with similar problems that you are talking about. Now it’s just time to inspect

[@EliasRizk53]

Single vanos ?

[@pilgrimhere652]

Thank you, I think that is the Problem with this 1992 Civic , I changed everything , it still crank but after a minute go off, Finally that is got to be the problem.

[@c-losdodgertown5804]

Thanks for the help informative video. Noticed you’re in Alhambra I’ll definetly call you up for some work.

[@mariosegura4468]

ShopLifeTv i have a question my 2006 325i haz 90 thousand milles u recommend to replace the trasmission fluid?

[@romanleal3499]

Could you do a oil catch can conversion, or video about the e46 oil consumption issue?

[@kentpayen8848]

Wow nice video. I never thought about the vanos seal will cause a lost of power. I do have a tank vent vavle code. I can't figure out what it could be. I change the vavle no change..beside the vanos seal and the thank vent vavle. What other issue I should look at

[@thevisionary2927]

Hi, My 2006 X5 E53 3.0i runs sluggish and the "After" O2 sensor needs replacing. I went to a mechanic but he dismissed the idea of the sluggishness being related to the O2 sensor. I'd appreciate if you could advise and identify any other areas that might need attention. The truck has 200k kms on it. Thanks.

[@michelleperkins3620]

Hey Jason I'm a new BMW owner and my 2003 530i is running like crap when I start it or sometimes when driving. If I take these off so I drive around a bit with these connections off?

[@JesusRamosMusic]

Hey Jason. So how do you remove those catalytic converters sensors first off?

[@chuddy2004]

Hey Jason, I replaced my downstream 02 sensor and cleared the pending code P013E but the check engine light comes back after driving 15 miles. The OBD II say delayed response- rich to lean bank sensor 2 after replacing Bosch 02 sensor. The car drive great but the check engine will not cleared system. What do you recommend?

[@bluesdirt5889]

Could you use a laser thermometer and check inlet and outlet pipes on converter ?

[@mikeh6740]

Good info, thank you very much for making the video!

[@stephenphilpott6772]

Hey bro, my bmw 330ci 2002 runs fine without any problems until I turn the engine off say to stop at a cash point, when I turn the engine back on it seems to loose a little power, drinks a little more fuel and tends to stall pulling off sometimes, any ideas what may be causing this?...Cheers. .ste👊

[@robertpersaud3626]

Hey there, I have a 1997 M3 which looses all electrical power while driving. I pull over and disconnect the battery for a couple minutes then reconnect it and everything is fine again. Usually happens when I am going fast. Any advice will be sincerely appreciated.

[@flat_life750]

hey jason i,ve hit you up on IG regarding my 06 X5 transmission fluid change and all that. but now all of a sudden turned it on, on Sunday and it started sputtering and it wouldn't go past 5 mph from dead stop then it gets going but while sputtering down the road also it sputters while sitting idle. service engine soon light also came on.

[@jasskhinda1732]

Hi. I have a bmw 316 ti. 2002. The acceleration power is low. And i have no idea where is the issue. Can you please tell me ?

[@deegha]

bmw e46 318i, when i put the ignation to 2 (before i starr the car) i dont see check engine light normally i see that on other cars... is this normal? coz i hv been testing this on few cars and every car has this problem..

[@Marty_Deslions]

Hey I have a question. My 1997 523i altenator was replaced. After the pickup, now SOMETIMES (not all the time) it feel sluggish above 2000 rpm. Like you press the pedal like 3/4 and still its very slow. What could be the cause? Also since its not all the times but only now and then. Vanos? camshaft sensor?

[@azamalkhairi3902]

I have severe lose of power in my BMW 740, 2006. While scan with Computer it gave error for O2 sensors before catalyst converter. Any suggestion is highly appreciated

[@thySerge]

Have you encountered a battery drain happening every couple of days on any e46? Had this problem last winter and replace the FSR and got a new battery seemed to fix the issue, but it has came back. If i don't drive the car for a a day or two, the battery is dead the following day. Also I notice that my heating is not working (not sure if its related or not), the reason I mention this is because during Spring/Summer/Fall the problem is gone. Any suggestions? I love my car but this is so freakin' frustrating.

[@victoriafausone7347]

Good advice for sure. My problem 2012 Chevy Cruze occasionally loses power and will not accelerate, then works fine again for a few weeks. This happens over and over again. I hear nothing loose or rattling in the catalytic converter. Could there be something temporarily clogging blocking the exhaust flow. Sometimes I will get a catalytic converter inefficiency code. How can I further troubleshoot this problem?

[@exige3604]

Hi Shop Life...I own a 2004 350z automatic. Couple days ago, getting on the freeway, I pushed the accelerator all the way to the floor to gain speed. Usually, the car will go into a lower gear to gain more speed, like a overdrive feeling! Nope! I then removed the throttle body off, cleaned the MAF sensor too. Still still slow slow instant response. The car will go....kind of cruising mode to gain speed. After that went to AutoZone to buy a new MAF sensor....that didn't work either! And btw...no check Engine light at all! What to do? Can you help??

[@slaughterevil8142]

I have a 2007 Lexus IS 250 manual , I have it straight piped but it does the same thing when sometimes I go full throttle, it seems like the car worked better when I re fill it with fuel. Do you think it’s the fuel pump?

[@besofacacia6103]

Man plz answer my question. i bought 2.5 2003 automatic 2 weeks ago. 0-100 kmph is 11 seconda shown on obd2. its terrible. today we tested fuel pressure and it was 3.150 bars when engine was running at idle. can it be the reason ?

[@mohamedly5557]

Mate thanks alot, you made it easy and simple 👍👍

[@mikeoneill7360]

I like the o2 sensor test, thanks.

[@braueydesign]

I have an issue with my X5 2003 where it randomly decreases RPMs and then ramps up again this pattern could repeat several to 30 times and then go away (all while driving the car) and then come back again if any suggestions much appreciated

[@boxlight2888]

wath could it be if im in 2nd gear at 4k rpm all good but then when i change to 3rd i get power loss like the car wont go past 1-2k rpms with my foot down wath could the problem be?

[@larrygallegos2922]

When i pulled the motor out of 2005 BMW 330xi automatic AWD there's two hose coming off the transmission . One was hooked up and the one coming from the back of transmission which is a hard plastic was not . Does anybody know if that's a vent that doesn't hook to anything and if it does hook to something where does it go . Would like some input if someone knows. Thanks

[@jaliscocortez5651]

Biggggg question to anyone who knows. What brand o2 sensors do y’all recommend me to use on my 330ci e46 ???? Need new sensors ASAP

[@kavsurjoo]

Hi I’m experiencing that power loss description but on my BMW E30 325i Engine Code M20B25 any ideas on that one ?

[@kleverAgudoMUSICai]

My bmw 335i losing power can it be due to map sensor also farenhein stays at 180 even though I drove for 2 miles

[@bigmwwe]

@shoplifetv car idles bad and no check engine light, done camshafts sensor intake side . Spark plug and the wiring forgot what you call it the thing that goes in the spark plug. Cleaned idle control valve and changed the boot around the air filter box . I would really appreciate it if you could just say your opinion to where to look more ? M54 engine E39 530i 2001 .

[@paulg5973]

Hey Jason,I have a question/video idea. I own a 2004 330i zhp. I picked it up about a year ago. I used your video to help me change the oil filter housing gasket. I saw oil on the engine, but I thought it would just evaporate as I used the car. Occasionally I get a bad smell from the ac/heat vents. Could it be the oil on the engine? If so what is the best way to clean it. Thanks for your help, Paul

[@the_flat_earth_warriorz]

Hey ...how ya doing...a question ...my 02 525 wagon drives good and then hesitates. I shut engine off and then runs good for a while and then does it again ...any ideas...I put alotnof stuff new...throttle body, tune up ...new boots vacuum lines....I 5hink it could be either DME or Cat converters...had diesel in gas before all of this....any help, thx

[@CZUNIGA36]

Amazing. Thanks for this video... it helped me....

[@nitrosystema9977]

i have the same issue, i experienced this after changing fuel filter, can this be the reason for this ?

[@EB2-]

I had a bad ccv and maf sensor. I replaced the maf sensor but i didnt do the ccv. Since i did maf sensor, the car shuts off at low rpms. I have a 03 330i. Is there any suggestion on this issue? Please respond if youre able too. Idk if fixing the ccv will fix this.

[@joyace9674]

You are so right thank you 😬👍

[@EB2-]

Can a throttle vacuum leak be a reason also? This power loss literally just happened to me but ive had a code for a vacuum leak for like a month bcs im saving up money to just re do my entire lines and hoses but i just experienced severe power loss. Please tell me this cant be transmission related also? Thanks man youre very helpful in your videos.

[@tonboy8518]

Is there any DIY for cleaning catalytic converters - E46 325?

[@Anyonewhos]

Yeah so i have an e46 compact 318ti sport. It's 50/50 if i have power or not. So for example, I'll be driving with power and the mpg needle will always go to max when i put my foot down in 5th and when it decides to lose power it will then be stuck at around 30mpg and will struggle in all gears to pick up speed. How i fix this is dangerous as i turn the ignition off and on again and suddenly I'll have full power back. Also it struggles to start after a short stop like refuelling. And in the mornings it takes a good while for me to have any power at all. I'm struggling to find a diagnostic here. Any help?

[@flipztuh24]

Do put the car in idle after you take out both o2 sensor?

I drive an 04 tiburon gt v6. Out of nowhere it started driving like ass. Like the acceleration isn't really there. And the rpms stop going up at around 3700-4000 rpm. I'm not getting any lights. I can get it up to speed as long as I shift early but it's taking forever to get up to 50-60 mph and I really dont wanna keep driving it like this. :/ any tips before I run it to the shop?

[@stealthincognito3321]

It sounds stupid but the parking lights in my vehicle won't cut off after shutting off the vehicle. I was told that the grommet is worn out in the brake pedal and that has something to do with the power loss with the engine. It all just started happening at the same time. Could you corroborate this hypothesis. I have a hyundai sonata 2012 limited

[@barryzelcer7909]

you mentioned vanos seals. I have an Opel Zafira - and experience sluggishness between 2 and 3 RPMs. My cat was busted replaced it, but I don't feel like I've addressed the 'real problem'. this video is super interesting to me....but I've never heard of the vanos seals issue.

I saw your videos about bmw cars, I have a big problem with my E46 BMW 316i automatic transmission engine n42b18a. The car turns off when it is on minimum rmp of engine. (600-700rpm) I have controlled sensors, MAF, MAP, air tubes, throttle sensor, I put a new chain, controlled ecentic sharf valvetronic, I changed electromotor of valvetronic and oil of engine is new. Everything works ok. The problem is not solved yet. When I check for errors on pc, shows only o2 sensor with error. When I unplug the cable of valvetronic the problem fixes, but the car has so reduced power. What I can do? Do you have any idea? Thank you so much. Have a nice day. Xhei

[@kiwiexotics1982]

Hi my BMW 318I 2004 E46 idles fine drives fine sounds fine Drives like a GEM BUT... As Im driving the engine goes into a limp mode doesnt go over 1000rpm's and doesnt go over 20kph. Then after a few seconds goes fine again. It does it sporadically it will do it every few seconds then wont do it for a few Ks Ive had 4 garages my icarsoft BMW scanner and a foxtell 301 and noone has found codes NO CODES at all. So Driving along fine cuts out to 1000rpm and 20kph doesnt stop or stall then it can take 2 seconds to 30 seconds to kick back into normal operation. COuld this be the catalytic convertors? Hope you still view this and can help with some advice. Thanks Ron @ Kiwi Exotics.
