[@spozz6633]

Thank you for showing this video Sweet Project Cars. I also experienced the same thing last year but did not know why it happened and continued to send it to the mechanics. The mechanics say that the fuel injector needs to be changed but does not look like new. and now after being shown by Sweet Project Cars it will save my money in the future if the same thing happens. Thank you very much Sweet Project Cars....the best teacher here...millions thumbs up

Wow! What am impressive diagnosis!! My hubby and I just changed the injectors on our 3.5L Maxima.... You're absolutely right....Those seals do get hard.

[@SweetProjectCars]

Thank you very much, Rochelle! We appreciate the view and comment, have a fantastic weekend. mad Mike the hammer SPC

[@Ottonic6]

When I replace something like my injectors I try to go OEM which will run way over $100.00 for all 4, so knowing the injectors themselves were good, what I did was get a kit with all the seals, o-rings and on mine, new screens. Worked like a charm for under $50.00. A lot of times especially when someone has messed with them before they don;t take special care when installing them and pinch the seal (like on yours) which will end up with a fail. Another great video... Always a big THANK YOU!

I once had a lean on bank whatever error with my 2006 Chevy Colorado with nothing in the codes about my MAF functionality and it turned out to be a bad O2 sensor. Just goes to show how these little tricks and a decent understanding of how you can disconnect stuff or spray things in certain places goes an awful long way to diagnose something. Of course, having a $500.xx set of service manuals always helps, too! (Something I thankfully bought for both my truck and my 2008 Saturn Sky Redline.) Thanks for the video.

[@x-man5056]

When you vacuum leak check with Carb Cleaner or other, use the straw on the nozzle. It will help you pinpoint where the spray at the suspected leak source. If you need to extend it, use a piece of clear vinyl tubing. You want the spray source as close as possible to the item you are spraying. The spray will be more dense (spray fans out with distance) and easier to see the exact spot that's leaking that way. If you ever have to change 1 injector seal, change ALL of them.

My 93 Pontiac Grand Am GT with the 3.3L V-6 when put in park will surge from 500 rpm to 1000 rpm but when put in drive it goes away and drives fine until I stop at a stop sign or traffic light then idles rough until I give it gas to go. Sometimes it will stall when I stop like it's not getting enough gas. I cleaned the MAF senor but still does it. Could it be a vacuum leak or maybe some other senor I'm overlooking. Thanks for your help and love your videos.

[@SweetProjectCars]

If it only does it when it's in drive, just leave it in drive LOL. Did you use this amzn.to/3MjGFIu and only this when cleaning your MAF? Also, make sure that your air filter has been replaced. You will also need to use this here amzn.to/3VX5rRT use the whole bottle on half a tank of fuel. We are doing these things to rule out the least expensive problems out of the equation. If doing these things does not take care of your problem, use this amzn.to/3LOiiRO and this will tell you what codes you are pulling up, once you do this let us know what codes you received and we will get you pointed in the right direction Kelly.

What was the issue you were having with your car, the issue I'm having is my truck starts but takes a few seconds crank I'm thinking fuel pressure is bleeding off through the injectors via a bad seal.

[@SweetProjectCars]

Sounds like either your injector controller has taken a dump or your fuel pump has taken a dump or your injectors all decided to not do their job at the same time.

I would say you need one of these amzn.to/3PBL9ur with 10% OFF CODE :T9BRFI99 Plug this in and it will tell you exactly what you need to do Brian. It's way more economical than going to a repair shop my friend. Thanks for watching and asking, have a great week and all the best on your project. mad Mike

Is the maf test a reliable test because i did It today and my explorer stayed running and also found i have a vacuum leak around intake manifold. Id appreciate the response, thank you.

[@codycheney3401]

do you have a way to clean rubber floors like in mini trucks that didn't have carpet ? how about bed liners ? it can't leave them slippery but also look like new ?

[@SweetProjectCars]

So i jave a 2007 uplander.. Same Code..i pul the..air sensor off..car still running is the sensor bad..please

[@eeyyaakk6801]

hello friend! Let's say the engine is running, if the check engine light is NOT on, and I disconnect the electrical harness of the MAF sensor, and the engine keeps running albeit a bit faulty (?) , what does it mean? Is that normal?

[@ceciliafranceschi768]

I would like to know what spray you used. I am going to try this on my car. I have had mechanics diagnose not really. I will come back with results 💪

[@SweetProjectCars]

We used these Carb Cleaner amzn.to/2IbaUkt & Mass Air Flow sensor cleaner amzn.to/3qzQ969 Thank you for watching Cecilia, have a great week and all the best on your project. mad Mike the hammer SPC

i'm curious,why if you unplug the MAF and the car keep running or not it tell you is bad or not?the MAF isnt acting with the car anymore ... i wonder since i have a 2004 volvo v70 r having idle issue and very high consumption fuel,i have 2 obdii code "p0507 and p2187" and i believe is my MaFsensor, i have change all vacuum line and do spray test on manifold,injector etc with out any effect and if i unplug the mass air flow the car keep running but very ba,confirm probly your point ,but just wondering why lol , thanks you nice video btw

[@SweetProjectCars]

ratselop best thing you can do in your situation is to replace the MAF then you will know for sure also run a really good injector cleaner like this amzn.to/2qI4RNB

Air bag is also flashing some times....i am totally confused what to do.. Kind uour help please.. I am an Indian from Kuwait..

[@SweetProjectCars]

If you didn't replace all of your coils, now is the time to do so. Once you've done that start the car up and spray the top of the engine while it's running close to the intake and fuel injectors with this amzn.to/3ZH0X2q to see if you have a vacuum leak the engine rpm's will pick up if there's a vacuum leak, you need to spray around until you find which area is leaking. The other thing to do is this kzbin.info/www/bejne/aKasiZKCg7yriLs for no less than 24 hrs. longer if you can. Thanks for watching and asking, have a great day and all the best on your project my friend. mad Mike the hammer SPC

[@cubanhack3r]

Hey buddy! Ss always great channel!!! I have a question for you if u can possible help. I have a code for the same thing. I removed the sensor harness as u showed here and the car kept on running like it wanted to turn off but it didnt go off. Does that mean i need a new mass air flow sensor?

[@SweetProjectCars]

Jose that is a great indication you need a new mass airflow sensor hope this helps my friend have a great night

[@cubanhack3r]

Thank you thank you! Keep rocking with your channel man :)!!!

[@SweetProjectCars]

you are very welcome :)

[@alansanchez-cp5lx]

If it was a vacuum leak wouldn’t the check engine light stay on all the time? Having this issue with an 04 silverado 5.3 with intermittent check engine light and threw maf code… but had a buddy with a vacuum leak on his same model truck and his engine light stayed on all the time… he was diagnosed with a vacuum leak… verdict? Do i have a bad maf sensor or vacuum leak?

[@SweetProjectCars]

When you get the check engine light, check the codes at that time, that's how you will be able to tell alan. Hope this helps, thanks for watching and asking, have a great day and all the best on your project my friend. mad Mike the hammer SPC
