quick CEL question

jaronfitz · 10-02-2012, 11:57 AM

I posted here about a week ago asking for help on a problem i was having when throwing a p0171 code and thanks to all your help my car is running amazingly.

When I unplugged my MAF my car instantly ran great, so I got some cleaner and cleaned it up and plugged it back in. It runs even better to my surprise. After plugging it in and starting it up I immediately checked my accessport and I now have p0102(MAF sensor) p0113(intake air temp circuit high input) and still my p0171 running lean code. i dont get it my car is running perfectly. Only mods on the car are a turbo back and a stage 2 tune.

any input?

Both the maf and iat are 1 sensor. Get an oem maf sensor and that should fix it. Or if you can switch mafs with someone and see if it fixes it because mafs are $$$

^^Agreed, try switching MAFs first. As, a new MAF is around $300 at some places. You can find used ones for around $75 TO $90 in the classifieds on here.

Don't buy an autozone or oreilys one if you do end up needing one. Get oem

Agreed. I bought on from Napa and the scaling is no where close to factory. In the cooler weather, I would max it out during a wot pull and I'd throw the high input code. Switched back to a factory one and so far no codes when cold out.

what did you clean it with? that could have made it run bad till it "cleaned itself" or dried it off.
