Missfiring On Idle..

[dori34]

what could it be?

idling in traffic and i can feel a cotinuous rumble in the engine bay as if its missfiring, comes and goes, it isnt often but it is definitely there.

doesn't miss when revving or when im giving it.

any ideas?

Also i was having idle issues before when my AAC was connected, i have disconnected it and the car idles fine. is there any harm done to the car if the AAC is disconnected and driven like that?

or is there a way to connect it up, reset the AAC or something and make the car idle fine when cold & warm.

also the car sometime stalls when coming to a stop, is this because the AAC is clogged up and would need a clean out?

Appreciate any help.

cheers

The AAC valve is there to control idle rpm - if it is disconnected it is not doing its job!

As for the missing idle whats your plug gap on and is there a vacuum leak.
