Thanks,

You must mean like the sludge problems in V6s that toyota denied for years and finally gave it?
You must mean like the continuing sage of transmission problems in Hondas? Now their Odysseys are throwing transmissions left and right due to underdesign?
You must mean like the inadequate rear brakes on some Hondas and I believe toyotas that wore out in short mileages?
You must mean like the drive-by-wire accelerator problems, the floor mat problems, and an unknown possible third electronic control problem that gives toyotas a ride-of-your-life acceleration? That toyota hid from the public and from the NHSTA for years starting in 2002 by misrepresenting the categories of reports and by using friends at NHSTA?
Do you mean those companies? And I haven't talked about Nissan and others.
Let's not pretend GM/C/F are the only companies who have things go bad.

Has the EGR ever been removed, cleaned so it doesn't stick open slightly, and put back on. it requires some brushing inside to get around where the grit can affect the sliding pintel going into the top part of the motor. Don't get solvent into the upper part.
Don't know if you've done it, but spray carb cleaner all around vacuum hoses and around the base of the upper intake manifold looking for spots where the manifold may be warping and allowing a seep of air under it affecting the ability of the IAC to control the mixture. Same for the throttle body gasket.

Check the underside of hoses, little and big, especially nearer the engine and the high heat.
Also try disconnecting the MAF sensor wires and start the car. They can cause stalling and poor running--but I don't recall high idling as a symptom.
An EGR valve can stick slightly open and a car runs rough and tries to compensate for the extra air it's getting through the EGR. Tapping on the EGR usually lets it slide closed if it's stuck open.
The crankshaft position sensor causes stalling. But high idling would not be a symptom.

I have a very similar problem! Did you ever figure out what the culprit was?

(Previously I had changed wires, plugs, fuel filter, and checked fuel pump pressure.) I replaced the EGR Twice. Then they found it was either a bad wire from the EGR or the PCM. Finally, (hopefully no more intermittant stalling) It was the PCM. It cost about 200 for trouble shooting the wires, and about 600 for the PCM Power control module, and a few hundred for initial testing before that. Hope this helps! The data in the forum here helped.
I believe that the 1992 has a thickness gauge that is used with it for installation to give the right gap between the sensor and the balancer. Later years setups had pins or something that determines the position for the sensor with no adjustment possible. It is possible to have it rub the balancer if not adjusted correctly. I am basing this on people's comments in forums through the years hoping it may help you avoid mistakes.
The balancer does have to be removed.

I have a 1990 Buick le sabre custom andis an awesome car just started to go down. The problem I have is the car turns on runs strong cold & wArm as long as I keep the heater on. But as soon as I turn it off, nothing. Cranks but dosnt turn over. I've changed the coolant temp sensor and thermostat but nothing the problem still persist. Next I think I'm going to change cps but I would like some insight from some people with experience. Thanks alot guys and girls
Do you mean that as soon as you turn off the heater blower or turn off the dash control with the OFF switch the whole engine shuts down?

Hot start issues are often related to fuel pressure or fuel delivery problems. If possible, doing a fuel pressure test while the engine is hot (pressure while cranking) might reveal something.
