What kind of minor work on a 91 F-150 are you doing? I have an 88 (same style) and minor work on that truck was pretty easy to do in the driveway. If turning wrenches on your truck really isnt your thing, but you'd like to give it a shot, I have done my fair share of work on my truck from wiring trailer lights to rebuilding the motor. If I cant help you with any questions you definately found the right website full of other people who certainly could!
I'm looking too...I need someone close to East Mesa, that is good with diagnostics, and can handle a modified Expedition (Kenne Bell SC, K&N intake, Superchip) Most of the mechanics I've spoken with (at the regular, non-performance shops) don't have the knowledge, it seems, or the patience (??) to deal with the SC. AZ Speed & Marine, in Chandler, installed the mods, but since my check engine light is flashing, and my #6 cyl appears to be dead , I don't want to go too far, and I've already used up my free tow for this incident.
