Service Engine Soon
Ok so I have an 2002 convertible and I haven't done any mods in 2 years. I have off road h-pipe and flowmasters, and mac cold air. I did buy the MIL eliminators, however I think this is a new problem cause by a missing air filter. My air filter seemed to be missing for about a 1-2 weeks. The check engine light came on and at idle the rpm gauge is a lil shaky. Going from 750 and dropping as low as 500 for a second or two. this occurrs a lot when im braking as well. Any Idea what the problem is? What should I do to fix this? Car has apporx 65K on motor. I bought a new filter of course, but I just dont think the car is running great right now and am a little scared to drive it hard.
