Newbie questions, CAI and Idle Options

[Corvius]

Hey all, long time listener, first time caller. I bought my '94 GT about two months ago and I've been following the forums and messing around with the DIY stuff. I'm definitely still a newb to the engine bay but I'm learning, hehe. Anyways...

I put in a CAI I made out of 2" PVC pipe today, but I have a filter (no-name brand) that's 3". Everything fits and runs, I reset the cpu, but my idle is ...i dont know if its bad or not...usually (when warmed up) about 900. Is this too low? Should i try and find a filter that's 2"? Any info on this would be greatly appreciated.

I'll post pics of it tomorrow, but i was also wondering if my battery could effect the idle, cause i know its old.


p.s. I had tried a 3" pipe on the filter and fitted it to the 2" throttle body and it seemed to make no difference, possibly even hindered performance...i dont know if i was imagining it though. I read somewhere not to go too much bigger than your throttle body so i decided to try 2".

Thanks,
Corv

900 rpm is a perfectly fine idle.
