My buddy has an older civic with an intake headers exhaust. When he’s chillin at a stop light the RPMs go up to 2000 then back down to 850(idle) Just like back and forth, not really fast, just up for a second then back down for a second. What up with that?

Rep Power: 454 the older hondas have a problem with the IAC valve. replace it and your problem will go away. I cant remember exactly what the problem is, but my old teacher explained it to me about a year ago. I think it has to do with something leaking. not too sure.
