a day and then it started missing really bad idling fine but when you pushed the accelerator miss like crazy and would not go any where then the check engine light starts flashing and i check it with my code scout and i cant remember the code but it said cylinder 1 misfire i dont know which cylinder is cylinder one i check the plugs in the first two cylinders on the left side looking at the car spark plugs are fine do you think is the coil i cant test because the intercooler has to stay on or the car wont run and the spark plugs on the front are under the intercooler Someone Help PLEASE!!!!
