2006 Chev Impala - Codes P2135, P2119

Post by nickscarcare »

2G1WT55K869124906 This car has been in for repeat codes, usually both, but at least the P2135, test and never acts up while the vehicle is here. Customer has reduced power at times when the code is on. We have tried 3 different brands of throttle bodies, have done the pcm update, replaced wiring harness, can never get it to act up while it here. Anybody seen a repeat failure like this? Thanks.
Some people try to turn back their odometers. Not me, I want people to know why I look this way. I've traveled a long way, and some of the roads weren't paved.

Tough to diag with out the problem happening but id really check the connectors or the wiring closely. Especially around the fan shroud

I just ran this through two of my tech help programs and weeding out what you have already done and if fuel pressure is where it should be (there were a few fixes by replacing pump) pcm reprograming was the answer. Good luck on this.
