I just purchased a 93 ty and I wanted to find somebody in the Dallas/ Ft.Worth TX. area to check out the engine and tell me what shape it is in or if anything has been done to it before I start spending the $ on it.
if you wanna come out to love field tonight I can look at it for ya. I'll be flying in for about 30min somewhere around 2-3am. will be at the biz jet center.
i think the best way to learn about your engine is to dig into it. unless it is making some wierd noises i would assume that all is good. start with a good tuneup and fix/replace any damaged vacuum lines or wires.
