when starting it seems to be missing when it warms up it runs and idles great just on cold start up anyone have any ideas i have changed cap,rotor,coolant temp sensor plugs and wires are good and no codes
What did the plugs look like when you checked them?
I only pulled a couple on each side they were clean and no wear at all it runs great just hard to start when its cold
You should pull them all. Chances are you have a few that are dirty. That makes them hard to fire when cold but can get better as it warms up.
I will do that this week you may be right
Make sure the gaps are correct also, this can make a big difference on cold starts.
