The more information you can throw at us, the easier it is for us to take a guess at it.

ok i put a water pump and timing belt, spark plugs and wires , and egr valve the car will idle after start up , but will shake bad, and then the engine you die out , and i will have to wait a come of mins. and start it up

Did you do the timing belt yourself? Perhaps it's a few degrees off timing. Were the spark plugs gapped properly?

[knotters2006]

how do i find out if the timing is off a little bit, spark plugs yes

Get a timing light and figure it out that way.
