I have recently purchased a 1998 Jeep Wrangler it has a rebuilt motor, a k&n ram air system, ceramic headers, and magnaflo exhaust. It also has a 4" suspension lift these are all good things now come the bad. When I got the jeep it swam more than drive, it drove back and forth and the bump and steer was ridicules. To fix this I replaced the front track bar with an adjustable jks track bar this helped, but it still has bad bump and steer. I'm also told all my control arm bushings need to be replaced and whenever I make a sharp right turn my check engine light comes on I don’t know why. Also I replaced the serpentine belt and the jeep would not stop squalling, it got worse when I turned on the AC. I bought a belt that bypassed the AC to stop that for now, but summer is coming soon so I will need to figure that out quickly. The AC did not work before I bypassed it I was told it has a small leak I don’t know if my compressor is good or not. Also if I let the jeep set for more than 3 hours it starts real rough and sputters for a couple of seconds. I replaced the o2 sensor and was told the wiring to the starter might be bad, but the starter is good it’s just getting to much power. The last guy who had this jeep needs to be shot. If any one has any input on any of these problems I would really appreciate it.
