Hey guys so a while ago I made my own bracket that mounts the coil to the cylinder head. Just recently I've been having problems with my car. It all started when I went to the track. I ran my car and first run down the track it started having issues of serious bucking. I mean serious misfiring in all rpms. After some diagnosing I decided to change the distributor since my tachometer was acting funny, I figured the PIP sensor had gone bad, and it had a liftetime warranty. After replacing it the car was running great. I noticed a tiny tiny misfire maybe around 2000rpm but I didn't even pay attention to it, car was running great just driving it on the street. Took my car to the track today and very first run same exact thing happened, after the run was over, it started bucking very hard under all rpms, hard to even drive the car. This time I decided to just go buy a new coil from a parts store since I heard bad things about MSD stuff, figured I would give it a shot, after replacing it the car ran like an absolute champ, I felt like I hadn't got it to run this good in ages, I was convinced that was the problem. I actually drove it back to the track and put down a record time. But 2 runs later I started having issues, car starts bucking, not severe but definitely miss firing. I am starting to suspect that having the coil mounted on the cylinder head, with heat transfer through the metal bracket is causing it too get way too hot and misfire when it gets warm. Do you guys suggest I move it? Or should it really have no impact, I mean don't older cars have it mounted to the block? I haven't gotten a chance to look at my spark plugs because with the gt40p heads I have to take my heads off to reach em but I know I should probably change them with all these ignition problems right? I just realized that was a long post, hope someone reads it. (Oh, by the way I've pulled codes and nothing other than emissions code come up.)
