Well, I installed my Weapon R WAI Intake finally. Hurrah. But there are a couple things that don't seem right. First of all my check engine light is on now. It didn't surprise me at all but I'm not sure how to get it to turn off. Plus, when I give it gas I can hear a faint, high pitched whistling noise coming from the engine compartment.

I had my regular mechanic take a look at it while I had it in for some maintenance. But I'm loosing trust in him. I dont think he even looked at the damn thing, he just told me its fine.

If anyone could offer a little insite on any of this, that would rock.

I also have a wai, and at first the hissing bothered me too. dont worry its fine. now as far as the check engine light, when you took off the stock intake, towards the front of the car there was a black hose. it was a plastic hose that had a sensor attached to it. the hose really is useless now, but put it back in the car and plug the sensor into it and that should make the check engine light go away.

Well, I gave it a shot but unfortunately it didn't work, The light is still on. I'm not too worried about it but first thing in the morning when I don't have my coffee I always takes me a minute to realize nothing's wrong. Oh well, I know some people around here I can get to take a look at it. Maybe they can help.

Thanks for the idea though.

If you disconnect something important and turn the car on, the check engine light will come on. I was going to bore out my throttle body and I took the whole intake pipe off to look at it and put it back on and missed a hose or plug somewhere, and it came on. I figured out which one it was and fixed it but it was still on, so I had to disconnect the battery to reset the ECU then it never came on again. Maybe you should try that.

The hissing noise is air being sucked across the closed throttle plate. It's easier to hear because it's not muffled by the stock air box like it was before.
