I'm getting a; Powertrain ignition coil 1 tru to coil 8 control circuit codes can anybody help me with this? It's on an LS1 2002 Camaro. The car just dies all of a sudden, it recovers after about 15 minutes with the hood up (I guess it must be an engine heat related issue??) A couple of times it recovered by itself with only a momentary loss of power & it backfired once. Crank sensor ? The cam position sensor was changed about 3K ago with an unrelated issue. I thought it was symptomatic with a coil going bad but not all 8 at once !! Could the power wire to the PCM be intermittently open? ANy help would be MUCH appreciated.

Thanks

Is your car stock?

Well the engine is stock...it's in an RX7. It was running great since I got it on the road about 3K ago.

No help here?? It kinda starts during IGN 2 "START" position so I'm guessing that IGN 1 has no power. Anybody got a wiring diagram of the IGN 1 circuit ??

check the wiring to the coil packs. wiggle the wiring to each coil while the vehicle is running and that will determine if it is a wiring malfunction off the pcm. check that first...

Thanks I'll try that. Also I'm thinking of putting a bulb on the Ign run position to see if it goes out during the ignition control circuit issue. If it goes out, I hope it does... then the issue will be much easier to track on the power side of the circuit.
