SOURCE: Car starts then stalls once the engine warms up.

You need new timing belt and gears. Buicks gears are made of plastic, and become a big glob. Nothing for the timing belt to grab onto.

SOURCE: low idle stalls out

Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: car won't idle after battery change

Won't idle after battery change... SOLVED! well, for me anyway. :)

I just experienced the same problem on my 2002 tundra last night, and fixed it this morning after sleeping on the problem. Here's how it went.
I cleaned the terminals, etc., and replaced the battery, as it was 7yo and old and on the verge of failing.
Immediately after this, the truck would start right up but the idle would drop to about 100 RPM, then slower and slower, and eventually stall. Every time.
I warmed it up and drove around the neighborhood for about 45 minutes, thinking the computer needed to re-learn it's Idle settings, etc... No change.
This morning, I decided to go after the cheap and easy fixes first...
Inspect throttle body... it was filthy full of black sticky dirty/sludgy stuff. I cleaned it off using a rag and some brake cleaner. DID NOT spray brake cleaner IN the opening; just on the rag and then wiped all of the gunk out of the opening, butterfly, and inside as far as my fingers would reach with the butterfly open.
Reassembled everything, started truck... runs perfectly.

Dead battery? Won't run? Dirty throttle body? How do these all tie together?! Here's why (to the best of my understanding).
Over the past 65k miles, dirt and gunk slowly but surely builds up in the throttle body. At some point, the computer senses that this affects the air/fuel mixture or something of this nature. The computer compensates for this, and stores it to it's memory. Sometime during the vehicles lifetime, the battery fails or is disconnected. The compensation settings that the computer stored are lost when the power is disconnected, so the next time the engine is started it's telling everything to behave as default... but the car isn't in a default state, there's **** in the throttle body... or a bad sensor, etc.
I could be way off, but my gut feeling is that this is correct. My advice: Pull the intake tube off the front of the engine and clean the gunk out of the throttle body. It should be the first thing to try, since it's the cheapest and easiest thing that I can think of.

SOURCE: The car starts and immediately stalls unless I

Hey Jruthesq

The 850 is equipped with an Idle Air Control Valve (IACV) which supplies the engine with air when idleing (a necessity since the main throttle body valve is completely closed when no throttle is applied, thus the engine would lack air without the IACV when idleing). The IACV is suspended in a rubber mount on the front of the throttle body itself, and is easily removed and inspected/cleaned. If it's dead a good cleaning usually gets it going again. Also make sure that the air from the IACV is unhindered on its way from the IACV to the throttle body (it's actually common for the holes in the throttle body to be gunked up so bad by hardened carbon deposits that one sometimes needs a nail or even a drill to open it up again).

Just thought I'd mention this since you said that the gas needs to be feathered for the engine to start. When you press down on the gas the main valve in the throttle body opens up, closing the IACV and supplying the engine with enough air.

Oh and if your fuel pump relay is a green one marked 103 you should replace it with the new and improved red one. The relay is located under the fuse box cover under the hood. Remove the 4 torx srews holding the cover in place and you'll see the relays under there.

Good luck mate!

Car turns over then stalls.


try cleaning the throttle body (use an old toothbrush and some carb cleaner) and disconnect battery for a few minutes. If that doesnt help, you may need to replace the IAC valve. (idle air control)
