My car seems to run fine until I drive it for more than an hour like on interstate then it will start missing really bad until it cools down. Any ideas what might cause this? Also, I keep fouling plugs after only a few thousand miles and it is running really rich.

I changed plugs (fouled bad) and O2s (fouled bad). Car runs much better has crisp throttle again, but have yet to take a long drive, but will be making a 3 hour trip sat. less than a year ago I replaced icm coil plugs and wires and opti. I think the bad os caused the plugs to foul. could still be a bad coil or icm i suppose funny it only does it after driveing a long distance. -- 1997 Z28, M6, Ceyanne Red Metallic, 3.42 Posi, 355, ported heads, ported intake, Hotcam, 1.6 Roller Rockers, 3 Angle Valve job, 30# Injectors, Hooker LT's, ORY, Magnaflow, K&N CAI Posted By: 87bandit On: 08-13-2008 @ 17:03:24 Reply | Top | Edit heatsoak coil or icm possibly a bad opti --
