My buick starts but then dies imediatly. Just removed throttle body base in an attempt to clean and replaced it. It started right up, better response than i've had in a while, but would not idle smoothly, then died after 10-12 seconds. If I start it and floor the gas, it wants to run, but just chugs, then dies when I let off the gas. I, ve been trying to fix it now for several months, but weather and money have kept my efforts to a minimum. I'm now suspecting the idle air control valve, but i'm just guessing. I, d like a second opinion.

That would be a good place to start. I would remove it and clean it. Have you replaced the fuel filter?

Yes, I replaced the gas filter just a few months before it died. Put in new spark plugs and air filter at the same time. When it died, I was pulling into a parking lot, had to feather the gas to keep it going long enough to get it parked. My first thought was that it seemed to run out of gas. But I had 1/4 reading on the gas gauge and put more in from a can to be sure. Since I posted my question, I've removed the idle air control valve and cleaned it, made no difference. Any ides for the next step?
