We had that happen once on a '99 F-350, thought it was electrical........turned out that a vacumm line back near the firewall had come lose. The clamp we used to fix it was a lot cheaper than the egr and air intake valve we bought trying to solve our problem.....another lesson in checking the small things first before you go jumpin the gun.
