I own a 2001 harley f150 Ford truck which has a consistant problem, not diagnosed on several occasions by dealers, the service engine light continually pops on. I was told that the truck had to be in the shop while the light was on in order to diagnose. Shouldn't the computer record this information. It's still not fixed and now the truck is out of warranty.
