Tim told me you got your car running OK. Too much line pressure, externally adjustable from the outside. Glad is was simple. Sorry you had to drive all the way up here to get it fixed.
He put the HP tuner back on my car, FREE, trying to get it to work again, but again it failed. I believe it is Onstar that is giving me problems, and maybe the Onstar module on the Pioneer deck, cuz I still have the factory radio remote mounted in the trunk.
He also picked up a misfire on my #4 plug from the tech II scanner. Again, NO CHARGE!
I also picked up a front plog manifold while I was there. Hoping to get it put on this Saturday. I also bought a factory coil pack, and will replace the MSD's, as they have 100,000 miles on them now, and ZZP doesn't like MSD coil packs.
