My car has been runnin like **** latley. first of all it wont idle right, and it wont go unless i am over 60% throtel and under like 5 psi of boost. the car sputters, shakes and just wont move. sometimes i can get it just right but i look in my rear view mirror and all i see is black smoke, alot of it. and i started it up and unpluged the MAFS and it ran almost better. nowi thought you couldnt unplug it or the car would die, at least thats what happend befour when i unplug it befour all this stuff happend. any one have any ideas becuase i need to get the car runnin again sooon.

I have similiar situation, not the smoke though. Got adjusted nicely, but had 8, 12, 18 on trouble codes. Got another AFM and TPS from junkyard. Just put in AFM, and TPS shortly. Let you know.

but the weird thing is im not thorowing any codes....

My check engine light was not on either, I just tested for codes stored because I recently got the car. Are you checking for codes, or just don't see engine light on? I'm still new, so hopefully we can help each other, and someone more knowledgeable will step in.

No i havent checked for codes yet. Im pretty sure its the MAF because when i unplug it it runs fine so that sounds like a bad MAF but thats just me....anyone a little smarter have any ideas...???

Well, I put the "new MAF" in, and definetely better, but still have trouble codes 12 & 18. 4th of July and didnt get to that. I dont know any more, but maybe someone can give some extra info. From what Ive read, and what I have personally learned so far, a lot of my problems are related to vaccum leaks, and the TPS. So read up, and Ill let you know about my advancement on this issue tomorrow.
