Ok, I tried searching on this, but didn't have time to look through tons of results as I have to goto work.

2001 LX Sedan 5spd/MT.
AEM Shortram CAI

I've owned this car since 62k miles and now has 108k. If I remember right its had a wierd idle since I got it. Cold start and the idle runs around 1000rpm then slowly works its way down. I get in the car and drive down the street, come to a stop sign/light. While I'm stoppped with my foot on brake the idle is jumpy (~1200 - ~1800 RPM). Right after I take my foot off the brake the idle returns to normal 650-700. Is this a bad IAC? It makes me wonder cause my CEL isn't on. Can there be an error code without warning of the CEL? Also my exhaust manifold has been cracked for the past year. My brother brazed it on the front but there is still more on the back I assume cause I can still smell exhaust through my vents. Anyone else have/had a cracked manifold?

Thanks in Advance.

Woot!, getting my new struts tomorrow. Bout time I get rid of these blown stock POS thingers.
