Random misfire Problem
Alright I am still trying to figure out my random miss and i measured the coil. Haynes says says it should be between .8 and 1.6 ohms between the small terminals and I got .4 would this cause a slight miss?

alright that wasn't it. I am really getting fed up with this problem. when the car is first started it sounds good and does not seem to have a miss and if it does it is only a very slight one. After it is running for a few minutes it starts to misfire more the hotter the car gets. Anyone have any ideas?

Alright when the car is started from sitting overnight it idles fine and sounds great. The warmer it gets the worse it sounds and idles. It doesn't even reach full operating temperature and it misfires at idle a lot. What does this sound like for it to be temp related? Also the faster I accelerate the more it smooths out.

Alright i was playing with it a bit today. The TPS was a little high so i brought it down a little bit but that didn't change anything. I really don't know what i can check next or how to check it. Anyone have and ideas i can try?

Have you tried asking Jrichker, or possibly Joel5.0
