missfire

[carracer76]

I have a built 302 with gt 40 heads and a e 303 cam with other supporting mods. When I bought the car it was running fine. I did a simple tune up on it, now I am getting a bad miss fire on start ups and idle. We adjusted the timing a lot. Do u guys think its the plugs, I have them e3s in there , its was running good, but then started to tune it up a little and now its never been rite.

Make sure one of the plug wires is not exposed and grounding out. Best to find it at night with the engine running. Also, and this may sound silly, make sure you have the wires going from the dizzy to the correct plug, and that they are pushed on all the way.

I've never gone wrong with OEM plugs... while you're at it... replace all your wear items... Cap, rotor, wires, blah blah blah.
