Fuel trims @ 100% constant, few more ?s

[nined2tsi]

Why would all 3 of my fuel trims stay at 100%? They havent changed for over a week of driving. Also Im throwing a code for the Air Temp sensor. Isnt that in the maf? Could it be a bad maf? On the logger it reads 11 degrees all the time. I logged a full run the other day but was wondering how to post them on here so you guys can check em out. I never have done it and I cant figure it out. Another thing is my AFC. Its set at -3% all across the board. Runs really good and my timing looks good, about 17* WOT. Im still trying to figure out how to use it. Is there anyone local that is willing to help me out?

No need to start another thread........I installed my new EGT probe and it doesnt seem right. Now my motor is either running really really cool or somethings messed up. I double checked the wiring and everything but no avail.. At idle it drops below 600* and at WOT 6500rpm its right around 1000*. I would think it is impossible to run that low of temps.

Nobody knows? weird

You need to ask one questio at a time, and not 100.

Fix the air temp sensor CE light. Is that the only code, or are you throwing one for the baro pressure sensor, and one for the MAF?

 

[nined2tsi]

My bad. Yes actually how did you know? I am throwing the baro pressure sensor code. That and the air temp sensor code. Would this be the reason my fuel trims dont change?

Sounds like your MAF is unplugged.

If you're in limp mode, the fuel trims won't be active.

 

[nined2tsi]

Its plugged in. Could I maybe have crossed a wire or something when I installed my afc? Didnt notice that the trims didnt change until I installed my maf, 550s and afc. I am wanting to figure this out so I can actually start to tune my car.

 

[kpt4321]

Something is messed up, that is for sure.

Figure it out and fix it, and then we'll go on to problem #2.

 

[nined2tsi]

ok. I thought you would actually give some insight on what may be the problem since I am right now reading all of your words on afc tuning and what not and how much info is in your head. Ill go fix that problem that I dont know what it is.

I'm sorry, my cross-country ESP is not working at the moment, so I can't see into the wiring harness of your car to decide what is wrong with it.

I tried to use my multitester to check for continuity on different parts of the MAF wiring, but I can't quite reach from here at my desk. Can you drive the car a little closer?

You have a check engine light for the intake temp and baro pressure sensors. There's only a couple places that could be messed up. Go check them, and fix those two problems. Then go to the next one.
