Message I have a feeling its something to do with cylinder six not aftecting rpm's when i pull the coil pack. i have spark, i have compression, and i have fuel. but its not affecting rpms....... no ecu codes. that fuel not being burned off in this cylinder is going somewhere perhaps the plenum and the enigne when ignition switch is off is still igniting the left over gas even with out the coil pack (everything on the car is off except very low idle) I let the car do this for prob a good 30 seconds to a minute then pulled the fuel comp cable off then it got an even lower idle then finally died after 3-5 seconds. i don't smell an excessive amount of gas out of the exhaust so i am stumped.
im thinking PTU or ECU or even Fuel computer, i think im going to have a buddy meet me at home and swap parts till i find a culprit. If anyone has had this and fixed it i would love to hear ideas
