Tonyrodz's Tahoe Build Thread

Had the o2 sensor(Denso?) swapped out. Got a little better, but pretty much doing the same thing. I think I'll pull the plugs to see what they look like, then maybe change the maf sensor. I have a spare oem. Still no cel.

Gonna try to swap out the maf sensor. I already swapped in an O2. I'm not getting any other codes. Kind of sounds like it breaks up a little during acceleration. Any ideas?

What misfire? Not seeing any on the counters....

This seems off?
It's idling.

More like it sounds like it's breaking up a little while accelerating.

These trims look ok? I still don't understand how to read them.

i think you need to figure out that loss of communication thing you get all the time. pcm might be bad, or your got a bad ground or something, either way thats far far far from normal. could be all your issues.

The tuner had said he was having issues with communication also. Is there a certain ground for the pcm?

other then the common grounds not sure really. my hptuners also got cut off when we tried to read your pcm. maybe try moving the wires to the obd port while plugged in see if you can make it disconnect. the power port is also on the same fuse as the obd port, so if the power port also goes dark it could be a fuse box issue.
