alright so I have a ka24de which has a weird ass idle problem. Whenever I'm driving and then throw the car into neutral or if I'm already in neutral and then rev the engine, the rpms go up and then come back down to about 1500 rpms, sits there for a few seconds at 1500, and then goes back down to 800. Some more gay shit it's doing is when I come to a stop light or whatever and the engine wants to die and the rpms go from around 800 and drops really low really fast. I'm thinking that the iacv needs to be cleaned but I just want some conformation from use guys. Thanks for any input.
