Car has stalled every week or so for more than 2 years. Same problem every time: slow at light or to make turn or to exit off freeway, take foot off accelerator, engine stalls out. Always starts right up first time, no problem.

When I take it to dealer, they always say same thing: fuel pump relay. Replaced relay twice, no joy. Also replaced O2 sensor, distributor, wires, no joy. No diagnostic codes show up on tester.

Ideas? My gut says throttle sticks occasionally when returning to idle, but can't prove it. How would I clean throttle body to rule this out? What would I try next? Crank sensor?

Have you clean the air flow sensor plate some time they sticks.
