I have not. I called last Tuesday and they said they would get back to me, but never did. I'll probably give them another call today to check in and see, because this check engine light is starting to get old.

 

Update: Just installed 2 AC Delco sensors, also tested and found 12 volts at each heater wire. Did notice when I pulled the other two sensors out, the truck has been running extremely rich on the right bank. Still pulling P0155,P0135,P0154,and P0134 codes.

 

Seems to only happen with headers. I wonder if running a redundent Gound would help???

 

At this point I'm about ready to try anything. I'm surprised this has not been a problem before if it is possibly ground related though.

 

I have the same issue. When wheatley downloaded a factory tune back on my PCM, the check engine light came on on the second ignition cycle with those same codes. I've been trying to get a hold of him for three weeks now with no luck. I guess time to change tuner

 

I've been able to get ahold of Nelson, they had me check over everything and swap out the sensors. So far though I can't get them to send me another PCM, tuned or otherwise to verify that that may be the problem.

 

Update: Talked with Nelson again, they're sending me another PCM to try out, hopefully this will solve the issue.

 

I hope you figure it out... i'm

 

Thanks! I'm feeling about the same. If nothing else I just want to get something better than 12mpg out of this truck. That and the engine light is getting old.

 

I'm really curious to see how this pans out, im throwing all but 1 of the same codes in my HD with a BB tune and pacesetter lt's.

Best of luck, keep us posted!
