Does brands matter for 2002 silverado. Should I stay with a oem brand Delphi
How do you clear the check engine light? Thank you
I changed mine and the engine doesn't run properly. I disconnected the maf cable and runs well. What could that be? Could that be that it's not the proper maf sensor?
My Tahoe stalled on me in the middle of traffic this morning and I panicked and brought my car to a shop near my job. Once they determined it was the MAF sensor I watched this video. Long story short, I got this done in 20min in my parking lot! Thank you!
Thanks so much
Why only cover replacement. I have repaired many diferant codes and running issues with a simple clean of the sensor. My 96 suburban (not the same engine I know) was diagnosed at 3 separate garages with 3 diferant major repairs. I cleaned the maf and never had another problem.
$10 for a can of cleaner is my starting point.
Hello, great video I just replaced the mass air sensor and it went bad within a month, can you tell me if having a knn air filter would have an effect on the sensor by getting it dirty and failing?
Thanks
Super easy, just need one tool…. Chris
Lol
Mechanic shop $450.00
i subscribed 2021 september, because they’re so specific. i love the detail to step by step
Great video would love to hear it run with a bad maf sensor then hear it again with the new one for reference
Is it possible that the MAF is going bad without a check engine light? Only have a rough idle, troubleshooting. Thanks guys!
My 05 Tahoe CE light came on twice a few months ago then went off. Soon after that I started having issues that slowly got worse and worse. Rough idle, stalling, lower RPMs, but they all happen when its up to operating temp. When the engine is cold, it runs like a top, no issues. The minute it hits 200-206 I get random misfires, stalling, etc. I changed the MAP, no change. I also bought a Temp Sensor. I was told you can test a MAF by unplugging it and if your issues are gone, you found the problem. IS this true?
Great job well done it helps thanks
Would it be mine if my trucks keeps turning off on me? Like I’ll give it gas but when I let off to break it then drops below 500rpms and tends to lose power until it actually dies
Mine is a 6.0l chevy 1500hd n my trans n tcase went at the same time lol
Quick question i have a air flow sensor from a 2002 sierra 5.3 would this be compatible with a 05 silverado 5.3
Why doesnt the 1990 Chevy Silverado have one?
Ok for the at home mechanic..do this..like me
Remove the entire hose…inside the big box
Oh,,,there's a real dirty filter…oh,, ,replace it….lol..
Its much easier to take the entire hose apart from the sensor..
Belive me….there's marks that fit the rubber gaskets and hose clamps back into proper place easy….put a new filter in protect that 112.00 part….lol…i am….
Hey guys i need your opinion? I have a 2003 1500hd n everytime i push on the pedal n get to about 60km/hr my truck starts to surge n tries to stall till i hammer on the pedal
Very slick and simple. Great audio and video!
