gillbot Posted January 17, 2010 Report Share Posted January 17, 2010 update: change the TPS, nothing. Got my hands on code reader. have pending codes po171 and po174. lean in both banks. is there a way to check the 02's before replacing them since they are so new. have looked for vacum leaks and sprayed starting fliud around to look for leaks. any ideas? would love to find someone with a comp to see what is going on.... you have rear o2's still on? If so swap em, if not maybe borrow a set and see if it will run better. Quote Link to comment Share on other sites More sharing options...

Nitrousbird Posted January 17, 2010 Report Share Posted January 17, 2010 When starting the car from cold, the PCM shouldn't be referencing the O2's until they warm up (ie - car running in open loop) = if it runs rough when you first start it, it shouldn't be the O2 sensors.

Guest Removed Posted January 17, 2010 Report Share Posted January 17, 2010 unplug them and try it. spray eats 02's. but under WOT, the pcm dont even look at the o2's. Quote Link to comment Share on other sites More sharing options...
