Help! Two dealerships and a local mechanic have not been able to solve my car problems. When driving at any speed in any gear, my Lumina will start hesitating like there is water in the tank. This will last 5 to 6 minutes and then the car returns to normal. It will happen once an hour and if I am at a dead stop, the car will stall completely. This problem occurs if the car is cold or warmed up.
I have had my fuel injectors flushed, all new spark plugs and wires, and the local dealership claims all my sensors are working.
Does anyone have an idea what could be wrong?
