So I bought a 1995 Jeep Grand Cherokee Limited with 180,000k. 4.0L 2 days ago for 1000$, and I did a full tune up on it (plugs/wires/cap/rotor/fuel filter/air filter/oil change) and I'm still having a few problems. My oil pressure gauge is all over the place. My temperature gauge is fine, except everytime i hit the gas it drops right down to 0, soon as I let off it goes bback up instantly. My infinity gold CD player in it is a little mixed up, I hit 1 button and sometimes it does the right function, or instead does the function of the button right below it. And also it idles at 500 RPM, but it idles fine when im driving, other than when I'm stopped at lights and stuff it idles rough. Any ideas guys? Sorry for all the questions.
