If it would not be to much of an inconvenience I would appreciate a PCM pinout diagram for a 2003 Tahoe vin Z 5.3 flex engine 4WD Thanks for your time and consideration. I have fuel pulse but no spark so this may help to narrow it down. What a bummer not having the Jeep this summer. This is my post.

I am seriously lost here. I have a 2002 Camaro Z-28, hydrolocked the motor. Boom ! Bought a brand new ls3/525 hp crate motor. Installed it. changed out all the conversion stuff, knock sensors injector, front pulley assembly reluctor conversion devise,... has 342 rear end, built 4L60e tranny, 3400 stall, SLP CAI, tuned exhaust, It SMOGGED in California, thank god, The only problem I am having is High idle, severe warm up time to idle ( cam is 226/236/525/525 110 lsa) I had to switch out electronic TB 90mm for cable driven 92mm TB no adjustment left, drilled 2 hole in plate to try to get it to idle quicker runs rich needs air until it reaches closed loop by computer. I have the original computer from the ls1 tuned to run the LS3 motor, gauges still work and tranny shifts O.K.....Its crazy fast. any suggestions ? can I reinstall that electronic TB w/pedal and what about computer and gauges ? thanks in advance

You should probably start a thread for this and not derail the diagram/pinouts.
That said, is the fast idle stepper there and working? If you want drive by wire I'd consider a gen 4 computer/harness stand alone. Then this thread for pinouts/wiring.
