I have a 98 SVT and ever since I have installed the KKM intake it has been idling really rough. Around 500 RPM to be exact. My guess is that the computer did not reset itself when I disconnected the battery. Does anyone know how to reset it another way or if this is even my problem?

Just give it some time so the PCM can learn the KKM. I had this same problem after I first installed the KKM. Maybe you should also check all the sensors too and make sure they're all plugged in. Once I took the KKM out and forgot to plug the MAF back on and it idled really rough.

Did you drive your car w/o the mass air sensor plugged in. Also did your check engine light come on. I had this problem today, and my wife drove the car. The check engine light came on, and right now I have the battery disconnected in hopes that the check engine light will go away.
