The turbo cc is acting up againthis time its running rich. If ur cruising and go to pass its acts up, missfire and blows black smoke out the tailpipe. It only does it under modderat to high loads u can get to freeway speeds no problem. Anybody have anything similar to this happen? Sometimes we just feel like chunkin the freakin turbo setup on this thing. Btw running MAF not SD and the only codes it throws are rich on bank 1&2

Checked BOV, intake plumbing, temp sensor reads same as dash gauge. How do i go about chekin the MAF and MAP sensors? They have the proper signals at connectors and seem to check out fine on scanner. Also cheked the TB to see if it was opening proprly and it passed. Gonna chek the intake gasket and wastegate 2morrow maybe its stuck open?

When u came in for a retune did we talk about the o2 being bad? Or is that the other white truck?
Sounds like an o2 if the truck is acting up during closed loop

Its the turbo cc. We replaced the o2s in april, took both trucks to truck night at sar and on the last run the light came on. We got it checked and both banks rich. I replaced the o2s again today to see if that was it with no luck. We will be putting the 6L90 in tommorow and set a appt with u 2 check it out.
16,600 miles and its got all these problems.
Fixed it. Intake manifold gaskets were leaking under 3 psi. Runs real good now.
