What causes hesitation while driving, already.

FIRST BREAK DOWN TIMING BELT TO SEE IF MARKS ARE ON ONE TOOTH OF WILL DO THIS HAD SAME PROBLEM TWO MONTHS AGO. TIMING LIGHT MAY LOOK RIGHT BUT CAN'T SEE BEHIND THOSE TIMING COVERS.

IF YOUR VALVE TIMING IS CORRECTED, CHECK FUEL PRESSURE, AND TPS SWITCH FOR VALUES.

While driving, hesitation starts from the time I start to drive and no indicator light comes on. Problem occurred after timing belt replaced!

Timing was tore down and checked out ok, and most everything else was checked, but the fuel pressure. Will get to that next week. Throttle or idle sensor was not working, but new one did not stop the hesitation problem. While driving home from shop, the hesitation seemed unnoticeable! One thing was not plugged in, that was corrected, but forgot what, get back to you on that, sorry! Thanks so much for all the expert advice. Will be clarified next friday.
