Three weeks after purchasing this vehicle used, the car began hiccupping or lurching while idling, and had difficulty accelerating from second to first gear. Mechanic checked error message indicating cylinder miss fire and found that all spark plugs and one coil needed to be replaced. Problem continued and check engine light went on. Same mechanic checked error message indicating cylinder miss fire, and found rubber gasket on coolant tank mangled causing coolant to splatter over engine. Replaced cap. I took a 1200 highway trip with no problem. After I returned and resumed low speed stop and go driving, the problem resumed. This time, the check engine also indicated cylinder misfire, but a hose exiting coolant tank was ruptured leaking coolant directly on to the same cylinder that had already been replaced. Thinking we had finally solved the problem, the hose was replaced, the cylinder removed and cleaned, but leakage under car and splatter over engine continued. Car is lurching especially when accelerating uphill, and check engine light is flashing on and off. There is a hissing noise after I turn off the engine. My license plate has expired and I can't re-new until my exhaust is tested, which they will not do if the check engine light is on. What am I supposed to do?.
