Bret,
With respect, I don't think any part of the engine- idle cascade should be crossed off the list out-of-hand...he describes a car that doesn't idle unless he is on the throttle, "feathering it." One of the items to check in a car that doesn't idle is the ICV, along with the AFM, injectors etc. Doesn't mean it is THE problem or the ONLY problem, but it is on the troubleshooting pathway that should be logically followed.
It is free and easy to confirm its function so why not confirm it works and then cross it off the list? I doubt there's one "silver bullet" solution in this case.
I understand what you're saying, but what I'm saying is that in my experience with dead or dying ICV's on these cars, the cars will usually run just fine, but they will "hunt" at idle.
From the original description, it sounded like his problem was alot more than a hunting idle.
I wasn't suggesting that a bad ICV was not part of the problem, but suggesting that it was likely not the main problem- so it makes sense to me to try to track down the main problem first.
The red-hot cat doesn't sound good. Sounds to me like either a clogged cat or the engine is running wayyyyyy too rich.
I wouldn't worry too much about the hardwired injector harness connector, as long as it was wired up correctly, that shouldn't present a problem.
Also, I wasn't trying to be a d*ck about the order of repairs you had already made to the car, just letting you know that I can relate to your situation..
