Misfire problem
dr-fastlane - 11/8/07 at 04:17 PM

Bad luck today. After a couple of miles the engine (2.0.ohc EFI) began to misfire. When I eventually came home I changed the plugs, TH leads, distributor cap, rotor and drove it. Everything seemed fine. But when I made another run after a short stop, it began to misfire again. Stopped the car and after a small cool down time it runs perfectly.
I think the engine gets enough fuel because it burns inside the exhaust when it misfires. (load bangs)

Symptoms:
-Engine misfires on driving speed.
-On idle speed it runs fine
-starts to misfire when engine is hot or after standing still for a while after a run.
- Or misfire a couple of time after fast cornering!?

Any ideas what could cause this problem? Coil perhaps?

could some part of the ignition system be over heating due to the small confines in a locost?.

That’s what also thought, but after a couple of miles the problem disappears when the engine is still hot. Today I’ve found out that when the engine misfires and I’m hit the throttle against the floor the engine runs fine.

Anyone?
