ok my car is pissing me off. it has new plugs, wires, accel cap and rotor, timing has been set to specs, and it has a brand new fuel pump, fuel filter, and injectors. and it only misfires when the engine warms up. going down the road is fine and it runs on all 8. i tested the ignition module 10 times and it is ok. im stumped. any suggestions on what else to look at?

 

Have you done a compression test?

 

no i havnt yet. i have kind of been ruling that out cuz the engine only has 45000 miles on it but i will check it see if it will tell any secrets.
