I own a 2006 F-150. It has been a great truck for me but recently I got my first problem with the truck. As I was driving, the machanic light came on (wrench) and my acceleration was affected. As I depressed the accelerator, my truck seemed to sputter and the acceleration was spotty. I pulled over and ten minutes later the wrench light was off and my truck seemed fine. Abt. a month later it happened again and I pulled over, restarted engine, and continued on my way with no problem. I brought it to my mechanic who said he found nothing wrong with the truck. He said he accessed my car's computer and found that there were no logged entries in the system. Has this happened to any of you, or does anyone have any suggestions. Thanks in advance
