Did a service engine or a check engine light go on? I have a 97 and never noticed a service engine light. I'm going to look good today. If you got a check engine light go to autozone and have them connect the computer. They will give you a small printout of what the problem may be. It's a good starting point. My light went on for a bad EGR valve. Replaced valve, autozone reset computer and I've been CEL free since. :cheers:
