Probably not a valve problem but a firing order problem
run a compression test to check for valve and head problems before you waste time and money of the engine
could be a injector leaking

Which fuse correspondes with engine idle

I do not think there is any fuse associated with idle. This should be controlled (speed at least) by the idle air motor on side of throttle body. NOTE: a bad, dirty or stuck EGR valve can cause this issue, as well as a bad coolant temp sensor.

2002 Buick Rendezvous CXL will idle very high & idle too low & stall when going slow or stopping.Replaced IAC valve. Service engine soon light not on, but service vehicle soon light always comes on.

Check for applicable trouble codes. Some of the national brand auto stores will check codes for free.

You may need to clean the throttle body and clean those small passages. With a high idle block off mouth of throttle body, should have a big effect on the idle? There are several issues that could cause idle to act up. Vacuum leak--maf and or map sensor. Don't replace anything unless testing points you in that direction.

On the Throttle Body

Doubt it failed

Best make sure you have no cylinder misfires
& are not loosing throttle plate data or tps data

DO NOT replace parts
Have a professional road test with scan tool, to look at data

You need to do every thing to learn the vehicles systems

lack of knowledge

Get some CRC Throttle Body Cleaner & read the

M buick stalls when I am driving it. I have to pull over, put it in park and it starts back up again. never know when it will happen. Replaced fuel pump. Dealer cant figure out what is wrong. says it...

It doesn't really need to have the computer connected, a simple OBDII scan tool while driving will suffice.

I'm am assuming that when your Buick stalls it is when you are at a stop light or at any other time that you aren't pressing the throttle.
That problem is likely caused by a faulty or dirty IAC valve. The valve is an electronic choke that allows air to the engine when the throttle body valve is closed...hence, your foot is off the gas.

Less common problems for random in gear stalling is an engine-side/bank 1 oxygen sensor fault, a vacuum leak, TPS fault or CPS fault. But those also cause a starting problem as well which is not mentioned in your query.

2002 buick rendezvous "awd disable" lite comes and stays on.

The most common cause for this problem that I see is a failed rear "Differential oil flow valve". You would need someone to hook up to the vehicle with a scan tool and retrieve the service code to know for sure but the valve is usually the culprit in most cases. There may be a code that says something like "rear axle over temp condition" and this relates to the valve problem. There are other things that can cause the AWD light to come on so it's always good to check first before replacing parts as the valve is fairly expensive. Good luck, hope this helps!
