I re-torqued all of the intake manifold upper and lower bolts and checked for vacuum leaks. I also said to heck with it and replaced the tps, o2's, ECT and ACT. Fooling around I found the electrical harness to a thermactor relay completely corroded. No relation though. One of these days I'll rip all remaining smog crap out of the engine bay and really clean it up.
After all of that, it is runnning fine. Honestly, I think I wasted some money on those sensors and it was the GT-40 intake that just needed a re-torque. I haven't retorqued anything since my engine rebuild
but then, it's more fun just to drive the heck out of it!
