Just missed ur call Grant. I got another foot or so. It's pretty crazy looking out here but the county did a pretty good job this time. I just drove down to Tijeras and back so I'm going to pull codes and see what I get. I'll make it out your way after I get back and let you test drive the AE. It's a pretty cool program and I only understand about 5% of it. The PCM was a thought after the repeated KAM and ROM errors and the fact that every other system that communicates with the PCM had codes. This will be my first real drive after fixing up the ICP and removing the DP. Will post back after I pull the codes. News says roads are still crap headed east and gonna get more snow so I may have to travel on x-mas day.

 

I can't recall if I cleared the codes last night or not so I'm off for another spin. Idle is by no means smooth and it feels like I have a miss.

 

So after another test drive the only DTC I have is P0541 Intake Air Heater Circuit Low.

KOEO gives me no codes

KOER gives me P0476 EBPV Range/Performance, and P0541 again.

I'm pretty confident the truck will be reliable to Texas and back. I still need to figure out if all the previous codes were caused by the tuner or not so it will go back in when we get home. I'll run for fuel in the morning to see if the stalling issue is still there. I had to shovel so much friggin' snow this morning it got pretty warm before I drove.

 

That's a lot of snow. I figured you were busy today getting ready to head out. Wife was over by the mall and said it was a mess over there because I 40 was closed. Looking forward to hooking up with you sometime. Give me a call or shoot me a message.

 

Made it to Ft Worth with no problems. Thanks for all the help so far. I'll pick this issue back up after I get back from the holidays. I'm still interested to see if the truck dies on cold mornings but Texas weather aint cold. Merry Christmas everyone.

 

So here's the latest. Went to Texas and back with no major issues (now I need ball joints). The tuner is still out of the truck. I have decided to drive it at least another week without the tuner. I want to get a few more cold morning drives in before I call it "fixed". After that, I'll put the tuner back in and go from there. I'm hoping the re-do of the ICP harness fixed the issue. I'm not holding my breath since I did not see my Vref ever drop out before the repair. I still have not pulled the codes after driving without the tuner so that will be interesting. I still have not tested the ICP harness (or any of the others) with the link that Grant posted. If I don't feel like total poo (getting over sinus and ear infections) I'll do a bit more troubleshooting this weekend.

 

Hope that fixed your problem. Maybe we can GTG sometime. Would like to see the ball joint install and play with AE a bit.
