    A clogged fuel filter would be the most likely cause.

    The O2 sensor may well be the problem. Did you also check the air charge temperature sensor, cylinder head temperature sensor, mass air flow sensor and throttle position sensor?

    If the EGR valve was stuck partly open, it would also cause this problem.

    A bad idle air control valve could also do it.

    I hope this helps!!!

    thanks Joel,
    Problem is there through acceleration, wonk get much over 20 mph. Tested the intake air, mass airflow,cylinder head temp sensors. removed cleaned and tested the EGR and it is fully closing. Havent tested the O2 sensors because they are such a pain to get at, also I scanned it when this first happened and got codes for a misfire on cylinders 3,4,7and8. Guess I will have to check the O2's. Was planning on pulling off the Idle bypass unit tonight and checking it out.
    thanks
    Joe
