Customer Question
2005 Pontiac Vibe with...

2005 Pontiac Vibe with a 1.8L (8) Engine won't rev over 2000 rpms without setting any codes acts like a rev limiter is engaging. All cylinders are misfiring but not setting any codes of any sort. We already replaced the ECM and programmed to vehicle with no change. Ignition coils and plugs were all replaced as well as fuel rail and injectors (all factory new parts) catalytic converter was replaced as well as both O2 sensors. We are running out of ideas!

Hi my name is ***** ***** ASE Master Tech. Pull your plugs and check the tips I have seen a lot of new ac delco plugs that have ground electrode bent touching the center electrode shorting out and causing misfires if the mechanic did not check them be fore they installed them. I hope this helps.
