So the car is pretty much buttoned up.
Everything thing is done and Custom Tune from Pat G loaded.
Car starts and runs..... Good oil/fuel pressure and no bad sounds thank goodness
Immediately throws codes and is in reduced power mode.
P0123
p0222
po223 -was not on during last start
p1516 -Was only on during las start
p2119 - has disappeared during a start
I don't think the car is getting into the tuning and is running rich in reduced power mode...Idle is fair 800-1000 and at the most is will rev to say 1800rpms but that's it.
Possible things it can be...codes obviously point to TB issue
Bad throttle body - seems strange that I am still getting some movement and rpm (I have tried another TB and it didn't help)
Bad LS7 maf - There have been times that it has shown a maf signal on the scanner and times it hasn't (2.7 is the highest it has shown on scanner). I didn't have the pink/black wire swapped at first start up and car wouldn't run. Actually I did have them swapped and then was under the impression the Caspers IAT breakout harness swapped these wires so I swapped them back....bone head move so I swapped them and car started.
Tried the stock maf after changing the tuning parameters and it didn't help.
Bunk caspers harness
I did cut and extend the 6 wires for the TB plug and the gauge wire is a hair bigger. I am confident that all wires are soldered correctly and there wasn't a short as it was heat shrank and loomed....im about to tear that all apart and re do it unless something else jumps out as a problem.
bad cam sensor? ls9 cam, 3 bolt cam sprocket conversion , am I missing something here in the tuning?
Would a vacuum leak cause this? (I don't think I have one as of now)
All grounds connected , Strong battery
????
Could the reduced power be stuck on from initial start with reversed maf wires? (I have HP tuners and clear codes but they come right back,have tried disconnecting ground for an hour)
I'm at a loss and need some guidance and suggestions...I'm basically going to end up going backwards and throwing $$ at parts
