my mechanic as changed some type of switch three times and set idle on computer, but after driving a little the car does same thing.

dashboard not working?

When I'm driving the car idle high then it gets sluggish and take a while to accelerate then it backfires and shut off then it starts back up and continues to do that every day

Car has been over heating...replaced water pump and hoses, also did a flush. Everything was fine for a month or so, then had metal hoses replace...car ran fine again after a long distance trip. Now, car is back to over heating with the oil light blinking on and off...could it be oil pump? Also schedule to have head gasket replaced due to the over heating issue...to be on the safe side...err on the side of caution...
