Car Shuts Down At Red Lights/Stop Signs/IDLE, Help Car Shuts Down... Options

[themanjsq]

Hello, I've recently bought a 1994 Celica ST, The car sometimes shuts down when i come to a complete stop, the rpm would fluctuate between 800-500 shake and studder then shuts off, mostly at red lights and when the car is on drive. However, if i leave it on neutral at red lights it doesn't shut off. I've went to 2 mechanics and they fixed the tps sensor which help for a few days, but then the problem occurs again. I've went to a 3rd mechanic recently and now he's saying it's the transmission and he needs to take it out to figure out the problem charging me 695.00, which i think might be b.s. so i didn't go through with it. Spark plugs & wires are already replaced with NGK, transmission fluid was replaced with toyota transmission fluid, oil change/oil filter replaced as well, ANY HELP OR SUGGESSTIONS please thank you.

Idle air control valve. Guaranteed. I drove a maxims that would not run atall unless my foot was in the gas. Clutch in, stall, not moving stall, foot to the floor it ram like our always should. Iac should be.around 100. Just look it up at on auto zone . Com and get an aftermarket one or try to clean and refurbish yours

the idle air control valve at autozone is pretty cheap compared to others, duralast for $124.99 or should i get STANDARD for which ranges from $200-300. do you get what you paid for? or it doesn't matter the brand?
