miss problem
miss problem I have a good miss while on throttle. My car's throwing a lean bank code and a intake air temperature circuit. Could this be a maf sensor, or would it be another issue.
Mods are in the sig.
P.S. It smell's like its running rich. I think its just unburt fuel from the miss.

Are you talking about a miss at WOT or just part throttle?
This sounds like an 02 sensor is failing. They cause you to run rich and they also cause misfires. And NO, you will not get an SES light or code until its really really bad or its totally failed.
Spray the **** out of the IAT sensor in the lid with MAF cleaner.....maybe that sensor is failing or failed.
If it is happening at WOT....then it could be the MAF.

I've learned our PCM's are full of idiot light type actions. They're good for tuning, but these PCM's suck.
Also, these PCM's are not all the same. They work differently in different cars. They are not all created equal. Or at least they do not operate equally.

I think i have simulators for my 02 sensors, since i dont have cats.

You need to get a scan with an OBDII scanner while the engine is running to see how the 02 sensors are switching. You probably have one that is going out. They cause rich running and misfires when they are failing.
