see if you can get some codes pulled.....

 

The engine does run rough just before in cuts off. I got a code of a malfunction coil when the check engine light was on. I replaced the coil, engine still did the same thing. But now no codes are coming up when the engine cuts off. also when the check engine light is on the engine runs good. As soon as the check engine light cuts off the engine starts missing and cuts off. This is a good one ! but its real. Thanks

 

id start by checking the battery terminal and making sure the wires are tight, make sure the plug wires are properly connected to the coil and spark plugs......... could be grounding out somewhere....... new plugs, new plug wires.........

 

Thanks, It was the spark plugs and wires. Changed them out engine runs fine.
