I have a 96 850T with 220k, auto. I recently had the head gasket repalced (for $1250!) and when I picked it up, I noticed there was a slight misfire w/ CEL. The guys at the shop said it needs a tune-up (which it does). I had replaced the plugs in the fall, so I threw on some new wires. Still misfires.

Could the misfire be caused by a bad cap/rotor? If you could only get a new fuel filter or a new c/r, which would you replace?

The car has other issues, namely a slowly leaking radiator around the side tank crimps (I noticed that during the recent warm weather, the leak stopped, which I believe happened when the metal expanded enough to plug the leak), also just starting after picking it up from the shop. And my tires are still legal, but too worn for comfort.

Isn't this fun?

ps - they said what probably caused the blown gasket (in cylinder 3)was the lack of vacuum regulation on the turbo - a lot of my vacuum hoses were cracked/leaking, so I was running at max boost (15 psi) when flooring it.
Check your hoses to avoid this!
