Car idles fine. But when I start off from a stop, the car has a severe lack of power. It hesitates like this at every shift point untill it reaches cruising RPM's.

This is an automatic transmission. "Service Engine" light flashes. Anyone have any idea were i should be looking? Thanks Josh from Spokane.

You need t have the codes pulled. Take it t Autozone and they will pull the code fr free. Then replace what the code tells you to.
