HELP!! 2.2L poor throttle response and unconsistant idle

[waveslayer]

Well i replaced the timing belt about a week ago and got it to run for 3 miles like it used to. After shutting it off and restarting it the engine died and wouldn't start for the better part of a week. Wile running tests on it, such as timing ( which checked out) the engine decided to start again. Now it won't hold a constant idle and sometimes acts like it wants to die. It has poor throttle responce ( if u mash the throttle to the floor it will die), But if u accelerate slowly ( this is all while the vehicle is not moving) it accelerates fine.
It has :
New computer
New fuel pump with good pressure
New throttle possitioning sensor
New timing belt
The car runs the same with either computer in it, old or new.
Doesn't appear to have any vacume leaks, and when i try to set the idle using the jumper wire method it doesn't seem to be working the greatest.
All other sensor check out, but i was unable to check Map sensor and egr

Have you check the MAP sensor? Disconnect the electrical plug, plug the hose and determine if it runs better.

Did the engine run OK prior to the belt change?

[waveslayer]

The map sensor is working. If the engine is running and you disconnect the vacume line it kills the engine, this is exactly what happened when i did the procedure.
The engine ran great before the belt blew, all 40,000 miles i put on the car since i bought it. I have recently done further adjustment to the throttle positioning sensor and seemed to help, not cure yet. I'm just won't wondering how dead on that thing needs to be to work correctly.. Then should i re-set the timing after adjusting that. Fuel pressure checks out also.
It has to be down to timing and the TPS.

dumb question....have you reset the computer?

Sounds like your timing belt jumped timing. I would check the timing marks on the crank and the cam. If the belt was too loose then It could have jumped on the road test.
This explains it running well for 3 miles, then experiencing the problem.
The problems you describe all are CLASSIC signs of a jumped timing belt.
When you set the tension on the belt, let the spring settle, then add just a hair more, and you should be good.

Too little and you'll hear the belt flapping on the cover, too much and you'll hear it singing.

I saw that you checked timing previously, I am assuming that you ment spark timing, and not the marks on the cam and the crank.

If this doesn't work, I'd check the EGR.
This can be accomplished by removing the vacuum hose on top of it and plugging it with a pencil, or golf tee. Then road test it, if it runs fine then it is EGR, if it still has problem, then it is something else.

Please post results of checking the Timing Marks on the cam, and the crank.
Hope this helps,
Justin
