stalling problems

[black93sho]

I was driving my 1993 SHO yesterday on a 100 mile round trip to visit my sister at college mostly highway driving until I got onto campus. Any way I was driving around looking for parking and the steering was getting real hard like if it almost wasn't running the power steering pump. So I found a parking spot and called my sister to tell her that I was there and to come down and meet me. The whole time the car was still idling. So I was sitting waiting for her to come down and to meet me and the engine just dies. I wait till she comes down about 3 minutes and start the car it starts immediately and I drive away. Go about half a mile and sitting at a stop light the engine feels like it dies, goes to like half a grand and then totally dies. Few minutes later start back up and I drive to a parking lot where it dies while I'm stopped. I start it back up pull into a parking spot and it dies again. We leave it there while we go eat and we go back to it and drive it back to campus, drop her off and I drive about 45 miles home on the highway with a few stop lights and it was fine. Didn't drive it today, until I see whats up just in case. Can you please help me on this, my car has 94000 miles on it.

Sounds like a classic crank sensor issue. Can you check your codes for us please. Click the link in my sig, you can easily get them yourself.

Is there anything else it could be. It did not seem to me that it was the CPS.
On my old SHO it would die mostly when I was driving not while I was stopped.

It could be a few other things. The easy way to check would be to get the codes if any. Then start the guessing game if required.

The IAC is responsible for idle management.

It is tested during the KOER portion of the test if the test is able to execute.

How do you find the codes. I've never done that before.

Just read my first post again.

Everyone is missing the easy and obvious. Check your plug wells. I bet that they're filled with oil. Once the oil completely covers the plug you're prone to stalling issues. Especially if you’re running the AC compressor. It will want to stall when the compressor kicks off. Drain the oil from at least the 3 front wells and I bet your stalling problem goes away. I speak from experience.

The strange thing is that you may drive for weeks without this happening, and then it'll happen a dozen times a day.

I'd check and clean the Idle Air Control valve, too. The stalling at idle is what points me to it. I especially noticed it when coming to a stop from road speed like an off ramp. Never a problem starting, just would die at idle coming to a stop. Happened 2 different times: after 3-4 years, and again 3-4 years later.

Remove and clean with carb cleaner and use a rag and a stick to get in there a bit. It also pays to get a rag damp in carb cleaner and clean the inside of the throttle body and plate. It's an easy operation to do and you will find out quickly if it is the problem. If it isn't, it probably needed cleaning anyways

Located on the intake manifold, inside the "big intake loop" on the back side of the throttle body. Small sort-of cylinder-shaped silver thing with a 2-wire connector pointing towards the back of the car. 2 allen-head screws (metric). The bottom screw is a PITA to get off due to interference of the L-wrench by the snakes unless you have ball-drivers that allow you a bit of off-axis play.
