possible bad TPS, IAC, or ECT sensors

A vacuum leak or a faulty IAC (Idle Air Control) valve.
Check for leaks in vacuum hoses, check for a cracked or gunked up Idle Air Control valve, and check you throttle positioning sensor.

If it stalls at idle or when slowing down, it could be a fuel filter. Or it could be the ignition control module.
Possibly a stuck or sticking EGR valve.
