So every once in about 30 starts i go to turn it over and it starts and begins to misfire and wont stop. So i turn it off for a few seconds and turn it back on and its fine.. any thoughts? Ive never had to deal with computer controlled fuel systems so just need an opinion. Its a 4.0L OHV with 98,000 miles.
