99 Camaro v6
It has a stumbling problem at idle and no power while driving, this happens immediately
upon starting car, indicating to me it's not the catalytic converter. It has new throttle body,
new coil packs, new coil module, new plugs, new plug wires and new fuel filter, the fuel
pressure is consistant around 42 lbs and no check engine light on. Can anyone help with
Also the Reduced power engine light came on for a brief amount of time the other day, but hasn't since.
Throttle position sensor? Camshaft position sensor? The only time I have experienced no power is when I melted my cat because I was running 100LL aircraft fuel. Burns way to hot.
wouldn't there be a check engine code on a throttle or camshaft position sensor?
Maybe a second fuel filter has been Installed in the line sounds like Fuel delivery issue
you ran 100% 100LL!!!! I use a 50% 93 octane with 4 oz to the gal Marvel Mystery (sp) oil in the 100LL. This keeps the heat down... you may have burnt a valve. You need to do a compretion test on each cylender. ....your not running a higher compretion ratio? Was there a power defferance with the 100LL.
Never mind you didnt do that. Someone else did. compretion test wouldnt hurt though.
