I think I still have my old Autolites which were used for a little over a week. I forget if they're coppers or not. I might drop the gap on the NGKs tomorrow if the CEL comes back on. I reset it after my last post and has been off since.

I'm also going to have a friend who works on Volvos for a living look at it either tomorrow or Wednesday.

 

Did you say you have a MSD coil? I was under the impression that coil was only for high performance set-ups like stage III applications. That could be one of your problems if you are not tuned for performance, stage II+

 

Yes I do. How bad is it that I have it?

I've only been getting p0303 the last couple scans I have done.

It seems as if I have a sudden radiator leak now, but it only happens once in a while. After driving 45 minutes to school and idling in the parking lot, it leaks. I can't tell where it's coming from, but the passenger side plastic part of the radiator is wet. Once I drive home and park it in the driveway, it doesn't leak. Also when the engine is cool, it doesn't leak
