Had all the plugs replaced and one coil. A couple of months later the car was hesitating again, they checked it out and found a spark plug to be cracked. One day out of the shop and the check engine light came on but went off in a day. But now it has been a week and a half and the same hesitation is happening. Will have it back into the shop again because the check engine light is back on and hesitation is getting worse. Getting really sick of the monthly visits.
