So did the TB swap today, I also added in my thermal gasket too. But I have a SES light. The code was the P2195-Stuck on Lean. I want to say it said B1S1 also. So is this something to do with the TB? Or maybe the spacer? And how bad is to run lean?

 

The order I did was IM then thermal gasket, then OEM gasket, then TB. No leaks at all.

 

make sure youre intercooler piping is tight and that your using t-clamps, cause i had the same problem, and it looked like they were tight but they needed a little extra umph. i had the same code and said it was to lean and so far the cel hasnt come back...try vacuum leaks and your o2 sensor, prolly the upstream one

 

first: we dont have turbos stock

second: this thread was left alone over a year ago. he probably has fixed the problem by now or else they would've continued posting in this thread
