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.

Does it only happen when the car is hot? In my car 2 of the rod bearings spun. When they would heat up there was so much resistance on the rods from expansion it would literally shut the car off.

Also once it shuts off does it turnover immediately when you go to start it again? I went through the same crap trying to diagnose it, didnt actually figure it out until i got rod knock.
