I have a 1995 BMW 318IS it has no power what so ever when im at a full stop and i push the peddle it feels like it does want to go. I cant even gun on the on ramp to the highway. Engine light comes on and off every five mins. What could this be? Also it over heated the other day so i shut it off and parked it what could cause that?

I would suggest addressing the overheating issue first. It can be caused by low coolant, a faulty thermostat or water pump. If your engine is overheating the engine will lose power.
