I am working on a friends 99 Accord. It was totaled. Hit the drivers side door, fender, headlight, bumper cover, spindle, upper control arm, tie rod, tire/wheel, poked hole in battery and crushed air box. Everything mentioned has been replaced and have drove it. My problem is it does not run good. Idle is up and down like crazy. I was assured it was running fine before the crash. Am I missing something? Is their a vacuum line somewhere on that side of the car that is pulled off? Cant seem to find a thing off. It seems too big of a coincidence that the Idle air valve went bad at the time of the crash. Any advice?
