Idle shake

thank you. I tried jumping the ballast for a few seconds and didn’t notice any difference.

I did another compression test. Not sure if I just recorded the previous wrong. This one seemed pretty consistent

125,125,125,130,130,125,130,130

#3 plug looks gummy to me. The others seem good, the pics make them seem black but they were not bad. #3 seems to be sparking good but strangely didn’t hear a real difference when I would disconnect it.

Need a better ignition > like Mopar HEI conversion with the OEM available 60,000 volt E-Coils.

This plug looked just like your carboned up plugs. It burned itself clean with the HEI E-Coil conversion. Did not take much driving either.

Burned Clean..... right down to the white insulator.
