Hope someone can help me.
Just installed a Cold Air Intake on my wife's 99 accord...
Soon as I started it up to test, Revs shoot to about 5grand and starts pegging the rev limiter.
What did I do wrong....or what didn't I do?

I hooked the same tubes that were hooked to the OEM "intake"...noise baffle, more like it...

 

your ecu hasn't compisated for the more air your getting. reset your ecu if you haven't already and let the car idel for a while. it should be fine

 

sounds like a vacuum leak, the extra air from the cai is nowhere near enough to affect the ecu, but resetting the ecu is a good idea anyways, but as for the revving 99% sure its some vacuum hose that you overlooked or an open nipple on the IM
