Could it be the throttle body sensor? It's bogging down on the highway then goes back up. I've change the injectors still doing it new fuel pump, new gaskets don't know what else to try.

Thank you

Have you checked the timing control module? This is not the ignition control module it is a square box either mounted behind the distributor or on a bracket near the air cleaner. Let me know if you need help checking it and I will walk you through it.
