Hello guys.

I have a little problem with my 1996 ST202. When car is cold and outer temperatures are under 10 degress celsius (50 fahrenheit) car normally start and runs aroud 800-900 rpm. Then I drive a little, but when I stop at first traffic lights, engine dies and dificulty starts again and doesn't want to run on idle. After some more driving, when engine warms up, everything is back to normal. What may be the problem, air temperature sensor maybe? I have no idea how cold start system works on this car, but when engine is cold it should run around 1500 rpm until it warms up.

Any ideas? Thanks for your help!

Recently another member had similar problems. His issue was a bad vvti solenoid. lol.

I don't think this is the problem because I'm talking about 3rd gen 3s-ge without vvti

Ok. You didn't mention what gen it was so I thought it was the beams since you had st202. Lol.

Question: If I have faulty water temperature sensor, could water temperature gauge work properly, but not system for cold start?

check isc, take the entire thig off ur throttle body, make sure u dont take it out with the 2 screws infrpnt of the sensors make sure to take out the wntire thing from the bottom of the theottle body theres a gasket in there, make sure u clean the valve with brake cleaner and try ur engine them.
