Have you ever cleaned your throttle plate or your IAC bore? Are there any codes? If so what are they? What is your fuel pressure? Does this do this all the time, only when cold, only when warmed up, only on the second tuesday of the month at 4:15? You say you replaced the timing belt tensioner, did you change the belt and idlers as well? Have you checked for vacuum leaks? How many miles are on it? Have you ever changed the spark plugs?

There are a lot of things that can cause this. Need specific details to give a direction to go in. Stop throwing parts at it. You got nowhere and just wasted money.
