I have a 98 eclipse and it starts missfiriing after about 30 miles until it completely stalls. If i reset computer by unplugging negative battery cable it will start and run fine for a little bit like 5-10 miles. If I let it cool off for about 15 min it runs fine for a while also without resetting. Any ideas camshaft sensor, coil pack, crankshaft sensor or burn it. It has a 2.0 non turbo automatic.

Wow it could be the ignition relay too, but i just remembered the rear oxygen sensor was broken off this winter and hasnt really been on any long trips until recently. It also seams to be running rich up until it starts to miss, a little bit of white smoke, no not water but smoke, its just hard to check things when it is running good until you get down the road, I dont really want to carry the shop around with me.:screwy:
