1badass, sounds exactly like a plug wire problem. Every time ive burned or cracked one, i get the most symptoms (stumbling) on od especialyl if im going up a hill.

I love the wordchoice, "hairline fracture". Orthopedics on cars

 

The plugs, wires and coil only have 100 miles on them. The wires are not crossed or burned in any way. Pulled the plugs and look really good. I'm running NGK TR-55's and msd 8.5 wires. I don't know, this is really getting old having to keep tearing into this car. Thanks for the helpful info.

 

make sure the caps on those plugs are tight. I ran those plugs for about 200 miles. when i first put them on they were great, then my wires started arcing like crazy and I had some wierd electrical problems. I pulled the plugs and the caps on all of them had come loose (some were very very loose, like a few turns from falling off). I ended up throwing in some autolite ones w/ the fixed top and it's back to running good again.
