Listen to what everybody else is saying and fix your grammar and spelling next time.

Since you removed the timing belt, I am pretty sure you messed up your timing. So: check the timing and once you are done, CHECK it again.

After you do that come back to us.

Either your timing is off, you have very little fuel pressure or you have a large vacuum leak.

Could be your idle rpm screw stop. When I put a Modern Performance 60mm TB on my car, after a few years the screw stop broke off and the car wouldnt hold idle. It would just die because the butterfly plate was essentially fully closed when off the gas.

When I did my rebuild, I forgot to plug my SAFC-II back in... that basically disabled my MAP... anyhow, my car did the same thing. It would run, but wouldn't idle. It would also die if I let off the gas and pushed in the clutch while driving. I would just give your MAP a quick spot check. Make sure it is plugged up, and/or not bad.
