Hey there! I'm new to nico, and I just recently bought a 1987 4x4 se hardbody. Turns out that the guy I bought it from was a lil shady. When I looked at it, great tranny and oil fluid. After driving it home, looked again- oil as black as night, and the transmission fluid was the 'strawberry milkshake' color. Took care of that, but it has a lot of other issues. I replaced the timing belt, water pump, radiator, and hoses. The interior was filthy. When driving it home, I turned on the fan and it blew mouse turds everywhere. but it's a cool looking truck. Anyways, one of the issues it has is idling. I looked on the hood and it said that the idle speed should be at 700 rpms. When you first start the truck though, it idles at like 2,300 rpms and revs, drops down to about 1,100 rpms and then revs again. After you drive it for a while, though, it quits doing that and drops to a steady 1000 rpms.
Any ideas?
