My car has been down and out for a month related to the damn things. I have finally solved it. I put both header wrap and a fire sleeve on the wires that were burning. That is of course after siliconing/superglueing the wires to the block. Finally the z is up and running. Its running better than ever. Good thing cuz the front tire on my truck exploded on the highway when i was driving it today. lets just say I need a new rim on the front for that bad boy. I think im gonna get like 5mpg on this tank. I've missed it so much i got on it about ten times already and its only been fixed like 3 hours and its running better than ever. Sorry just had to share my excitement with someone.

I had a similar problem with my car after the header install, it sucks.

What wires and looms did you use and where did you get them? did you just get the thunderracing package?

 

being curious here, but what plug wires kept burning on you? which cylinder or cylinders?

 

Thunder Racing Package on both cars working like a champ!!

 

the universal MSD 8.5 kit for my car, and Russell OVC looms from summit also.

I have to comment on my mac headers being freaking awesome. It is so easy to change my plugs now ( which is anyother story) Yeah i even had a wire that was getting close and barely tapping the primary. 3 cyclinder back on the driver side .... OVC look a little tacky only cause i have gm parts moddified crhome valve covers. (going for a clean motor) so with a little patience I got the wire zip tied in place .... you just gotta check everyting out once in a while and make sure everything is in order .. hahaha glad to hear it worked out for ya .... and that the car is on the road !!!
