p0105 and p0172 final plea or the G gets curbed!!!
Well I'm rolling unregistered because I can't pass emissions! I have two codes one is p0105 (absolute pressure sensor), the other is p0172 (system rich). I've had both of these codes off and on since august of 05. I've tried just about everything. I'm begging for ideas and if your local a fresh set of eyes! If I can't fix this soon I'm parking the G and just going to get another car. Here is a list of things tried:

p0105:
replaced boost sensor with used sensor
checked line for cracks

p0172:
cleaned maf
replaced maf with used one
replaced maf connector
tightened intake
check and zip tied fpr vac line

This is the short list. There is a ton of other things I've done I'm sure. Some people have said I need a check valve in the map because it's not suppose to see boost! But if thats the case then everyone with a de+t would be throwing this code.

Please help! My car runs absolutely perfect! I've also gotten 27+ mpg with the last few fillups!

I have already asked over at g20.net too!
