Hello, I recently put a SKUNK2 Intake Manifold on my 98 prelude (non SH). Right now I am throwing a check engine light (which I pretty sure it is just the knock sensor that I busted …oops). But when the car is first started when it is cold, the engine revs up and down between 1300-2200 rpm. Basically as soon as I start the cold engine…it sounds like I have a little person in there mashing the gas repeatedly. As it gets warmer, it bounces between lower rpms until it finally warms up and then it idles pretty normal. Can you help figure that out?
Also, when I am in like 4th or 5th gear and driving about 40 mph or so, I can give it gas and the intake makes a whistling noise. I was wondering if that is normal or not. There are no vacuum leaks or anything that I can find. Do you know anything about that?
Thanks
