ROUGH IDLE AND STALL

1999 Hyundai Tiburon

Engine Mechanical problem
1999 Hyundai Tiburon 4 cyl Front Wheel Drive Automatic 120000 miles

I have a Hyundai Tiburon FX 1999 and I have recently replaced the radiator and transmission. Before I replaced the transmission the car started to die at redlights and it would jump and idle rough around the 3 to 4 rpm mark. It got so bad that the transmission was replaced by dealer and the car is still doing the same thing. I replaced plugs and wires. Is there something else that I'm missing. What else could cause this problem.

I question the transmission. To me it sounds more engine related. Has the check engine light come on? Have you checked for vacuum leaks? Fuel pump pressure?

Let me know.
