Bad Idle-Air Controller
I have a '99 F250 SD with the 5.4 L that, after starting, drops the engine RPM to around 400 for about 10 secs, then either stalls out or revs up to 1500 RPM and then drops to normal. The service guys at my trusty dealer say its a bad IAC. Since the truck's under warranty, Ford's paying to replace it; however, has anyone else had this problem? Thanks
