Thishappened quite a while back ...
i drive to work (school) one morning and everything is great - cold but great running car.
i come out to go home and start down the road. Bonnie start chugging and kicking????? really weird? turn it off - start it up again and it runs fine for about 30 seconds and same thing chugging and kicking.
worried about just about everything - rockers bad? did i get water in my FWI? WTF????
i give a call to the INTENSE guys, eventually getting ahold of Rogue(but much later after i was at the dealer). By this time i have a tow truck on the way. i get to the dealer and explain i bought the car used - it is still under warranty - and what is happening.
Talking with Rogue we figure it is a Closed/Open Loop issue. Which the dealer later agreed with.
Let me say the Dealership was Great! Dan, the service rep, at Jeff Schmitt Pontiac in Dayton really helped me out. How? Well, look at my signature ... just a few mods there, eh? Mods and Warranties are worse than oil and water when mixed. Dan took the attitude that these had ABSOLUTELY nothing to to do with the problem - which was correct in the end.
So, after much trouble shooting they explain that it looks like the MAF sensor is probably bad. R and R that - still no fix. It is better, but as soon as it enters the "loop" it starts chugging and kicking and dies.
what'* next? the PCM - no no no can't change the PCM dang it, i paid good money for that performance coding ...
Talked with Rogue again and he reassured me that it would be fine for them to put a stock unit in it with my mods.
What do you know? it was a bad PCM!!! that makes two PCM'* in less than 75K miles.
Bonnie is running great again - still need to get the performance codes blown back in, but i think i am going to wait until i get her up to INTENSE to have my cam installed (someday
Anyway - MAF and PCM were both bad - both were covered by my extended warranty - and get this ... the new PCM has a TEN year warranty!
if i forgot anything maybe Rogue will jump in, or i will remember more later and update this.
