When I took the car back out it was still popping at high rpms so I checked out my wiring and noticed I had a loose + and - wire on my coil so I tightened it and and the popping is goooone.

Problem Solved....... I checked my spark plug wires and the number 2 cylinder wire read nothing on the volt meter and the wire from my MSD coil to my distributor didnt read anything on the volt meter either. I put new wires on the car and it sounds alot better. The spark plug wires were Arcing...



Man, We sold you springs, rockers, carbs, and everyting else to diagnose the first thing you should have checked in the first place!

I am just messin with you but WTH? Laughing


Loose wires on the coil?

You need to go over that car and check all the bolts like I do every year for the hell of it.

Basic wires loose, scare the shyt out of me and I wonder what else is loose!

Yea I took my time and went over the whole car when I found the loose coil + and - wires on the coil. My car has tons in it. My spark plugs used to be jet black with carbon on it due to a weak spark and now since I tightened the + and - wire on my coil my spark plugs has been burning clean ever since. So I was actually having lean pops at high rpm due to a weak spark and not being able to burn off all the gas it was getting at WOT.
