2007 g35 sport 6mt completely stock, check engine slip and vdc light are one and card hard starts and run rough then runs normal then when normal operating temp it starts idle up and down between 1000 and 2000 rpm, car wont rev past 3500 rpm, I have replaced plugs, replaced vvt solenoid, changed oil 2 times, cleaned throttle bodies, checked for air leaks, check cats, swapped cam sensor from bank one to bank 2 and not change. any ideals.

 

Check coil packs for damage/bulging on the epoxy resin (smooth glossy surface on teh top) or burning ANYWHERE on the coil down the spark plug shaft. Also get the starter checked as well as your battery. Have you done the idle relearn process lately?

 

coil packs look good, I have tried ecu reset all the relearns but I'm still getting cam sensor code and can't get rid of slip and vdc light
