I have not personally done the intake manifold gasket. No visible soap bubbles anywhere along the top. Throttle body was cleaned and gasket replaced. Shaft o-ring is leaking slightly but not enough to cause a problem in my opinion.

Crank sensor replaced.
o2 sensor replaced.
Cleaned idle air control valve.
Checked and set valve lash.

Lesson learned, don't just let your coil driver flop about.
I still haven't tested the ECT, ill try and do that ASAP.
I do have a spare coil driver out of the junkyard laying around. Do they need to be mounted to the inner fender just to test it?
