Engine Performance problem
1998 Mazda 626 6 cyl Front Wheel Drive Automatic 140, 00 miles
my daughter drives this car while she is away @ college. We recently replaced her timing belt and water pump. When we picked it up from the mechanic, we were told one of the engine mounts was broken, the car would run, but it would be rough while in gear but not moving (say like at a red light). Boy was it rough. We had the engine mount fixed, but it is still rough while in gear and stopped (again, red light) but much improved over what it had been. When the car is moving it is smooth and sweet. Lately she has had a check engine light come on and the auto 'zone' type stores tell her she has a mis-firing 3rd cylinder. We have all new spark plugs and wires. I put some slick 50 fuel injector cleaner in it about 300 miles ago. Are these two things related? Could the rough idle be a transmission problem (it's about the only thing I have not fixed/replaced on this car yet! ;-} )
have the same problem?
