i have a bit of an odd problem.when the car is cold, i start it and go where i need to go, and stop it. 5-10 minutes after, i restart it and it's mising on the first cylinder. It had 2 month old msd wiring and i could see the spark jumping to ground. so i changed the wiring on the guarentee. the plugs are new from the begining of summer. i swapped coil packs as well to see if there would be change but none!only remedy is to let it cool down an hour or so. any suggestions? i think i'm gonna change that 1 spark plug.
