Hello everyone, I just bought a 119k mile 1993 black Lightning and have a few questions. First the truck idles high around 1000 to 1200 rpm and has a very hard 1st to 2nd gear shift. I'm thinking vacuum leak but would like to know where to start to diag this issue. Truck runs good once the rpms are up but fells sluggish off the line.
