My wife's 99 GC has just hit 90k. I don't normally do anything with it, I only drive it once in a while. I drove it the other day and it just does not seem to be running as smooth as it used to. We pretty much keep up on the regular oil changes, and Transmission fluid changes. I really haven't had to do anything on besides the brakes. So this weekend I am planning a tune up.
I am going to replace the plugs, wires, airfilter, and run some injector cleaner through it. Anything else that you guys can think of that I should do?
