So heres my problem when its dark I can see that the spark is actually grounding on the head and not the spark plug. Also when the car has been running for a while and gets to operating temp the wires are arcing on eachother. These are on fairly new msds. I have a set of taylors waiting to go on because I havent had any luck with the msds but what I am mostly concerned with is the fact that even the new taylors are arcing into the head instead of the plug....what causes this? Oh yeah actually the driverside has taylors on it and the pass side has the msds

 

Maybe some cracked porcelin on the plugs if it is grounding on the head. They just do that sometimes. I use NGK TR55's and have had no problems. Well, beside the Jet Hot LT's cooking the wires.
I would replace the plugs also.

 

yeah I also have jet hot lts and ngk plugs...I figured out a way to zip tie everything away from the headers though so that there is about 2 inches of clearance on each wire...I only had probs with the driverside wires gettin fried before I did it

 

Make sure your grounds are clean at the ICM , coil and ground strap......also use dielectric grease on the boots if you havnt. If you have allready used the grease make sure you didnt get it on the metal contact points.

 

I thought dielectric grease is suppose to go on the contact points...is that what its for?

 

No .....it goes on the rubber boot ....its nonconductive and is suppose to help prevent arcing. Clean it off and try again.
