My 89 xj has a rough idle, seems to run and drive fine. But its started to backfire. The guy I bought it from said he had to replace the computer and the timing had been out ever since. What do you guys think? And let me know if I can provide any more info to better diagnosis the problem. It has the inline 6 4.0, not the high output 4.0
