P0174

Got this code, looked it up, recommends that I clean the MAF sensor. How do I go about doing that? Take off cai, unplug it and spray it inside where the plug goes?

Spray the MAF itself inside and inside the plug?

I cleaned MAF and reinstalled it. T
Removed the code and drove it for 30 minutes. Check engine light popped up again same code. What else could it be?

There could be air getting in between the maf and tb. When I got that code the coupler behind the maf was letting air in. It could also be a vacuum leak.

Im not trying to hijac the thread but I am having the same exact problem with my gt so I'm interested in hearing the solution, I had one source tell me that a faulty PCV valve could cause this code but I havnt replaced it yet

Can't have a vacuum leak. Not possible Haha but def. air could be getting out lol. Just tighten down all clamps, secure everything, clean the TPS and troubleshoot. Might be a O2 sensor as well! It running kinda bad or what?

I think my O2 sensors are bad. Mine randomly lost power and throttle response today. Had to smash the gas for it to accelerate.

I ended up frying an O2 sensor because I waited to long to fix it. Now I get code p1131.

Just replace your pcv valve. It can't hurt especially if its stock. Easy as hell as well

If its having trouble accelerating, it might be the maf sensor. My friend put mine on and didn't plug it in so I drove to school and the thing too forever to accelerate. Then I found out his dumbass didn't even fully plug it in haha.

It just did it once when it didn't accelerate. I clean my MAF. Didn't look dirty in the first place...
