The thermostat should be good since you recently replaced it.

The O2 should probably be replaced.

Consider plugs and wires if it'* been a while

Cruise control in seperate thread.

No, i didn't replace the thermostat, but i tried it before, and its buried to the point where if I attempt to remove it, it'll round off the bolt head. So basically, the intakes have to come off. good thing they are bolted on by section.

I'll post another thread about what kind of thermostat to purchace.
Thanks a bunch.
