Update: I had fixed an air leak in the air intake hose at an earlier time. I believe that caused a host of issues from no power during acceleration to limp mode after several miles of driving. Also had a cracked exhaust manifold which kept vehicle from running for several months. During removal of exhaust manifold, I found the intake hose leak in the folds of the bellows.
Now that I think the air leaks are mostly fixed, the ISC when hot will not hold idle. In fact, when the engine is hot and switched off , it won't start or run unless given some throttle.
I've been advised to run seaf**m into the intake to clean stuff out but hesitate in case even more problems are caused by this treatment. I am going to try your trouble shooting methods of testing the resistance of the coil and maybe removing and trying to clean the ISC.
Should I put RTV on the gasket when I put it back together since it has to seal coolant as well as air?
What is the torque for the ISC bolts?
