sooo i brought my car back 2 weeks ago to get the tranny worked on for the 3rd time now. but thats a diff story. i get the car back late yesterday, and everything is good. shifts into every gear, rides nice. i didn't take it above 3 grand anytime i shifted. maybe 3.5 a few times. now today i'm coming back on the throughway, and the Check engine comes on. i go to autozone, and they run the diagnostics and 4 codes pop up.
1. MAF
2. o2 sensor
3. thermostat
4. multiple cylinder misfire (my favorite)

so, after this, i'm pretty pissed. i take my car to my house, and my buddy drives me to the dealership. no mechanics there on sunday. so i talked to the saleman i bought the car from. he said that the mechanics could have forgotten to reset something, and something is fucked up. i'm hoping that its that, and can just be reset. but, knowing my luck, the **** is fucked up. idk what to do.

ecm, they will need to reprogram it or replace it, theres a bulliten on that


well if anything that would be my guess

 

I'd also have to say its highly doubtful that any of those codes are real. Is your car running crappy or different at all?

 

If your engine was running fine at the time, they are most likely erroneous codes.
