on a cold start i hit the gas a tiny bit really quickly and held it there, the rpms dropped really bad. normally due to my dirty IACV or the bogging w/ my AEM cai i just ignore it because i know it's nothing to freak out over, but yesterday the rpms dropped really badly, i'm talking about dropping to the point to where it's getting ready to stall out on me. but that's not the end of it, it's not like when i hit the gas like that the rpms just dropped real quickly, it slowly started going down, it went from 1,000-700, held there for a couple seconds then 700 to around 300 and then i freaked out and let off the gas and it went back up to around 1,000. is this supposed to happen? what do you guys think? thanks.
