2004 Ford E-350 Super Duty 5.4L Misfire, MIL Lamp on
Ok guys, i'm not the best driveability guy out there, and this ones got me stumped. This is a minibus that sits at idle a lot. It came to me running fine but when i let it sit at idle after 10 or 15 minutes it starts to missfire and the fuel trim goes up to 22...
