I have an 86 trans am with a 305TPI. I have a slight miss at lower rpms and don't know what could be causing it. The car has new plugs, wires, distributror cap, rotor, newer fuel pump and a new ecm yet the miss is still there.

Does anyone have any ideas as to what I could try or things I should check?

Thanks for your help!

Does it happen all the time or when the car is hot?

 

It seems as though it is always there, but it is worse when the car is hot.

 

Possibly the ignition module

 

What is the difference between an ignition module and an electronic spark control module if any? I know that the electronic spark control module sits near the relay bank on the firewall. Where is the ignition module?

Thanks
