Hi,

 

I have a strange issue i haven't encountered before and hope someone can help.

 

When i come to a stop and am completely stationary, the revs go to to about 3000 on their own for a few seconds before coming back down. My foot is nowhere near the accelerator at this point.

 

Has anyone else had this happen?

Does the engine have an Idle Air Control Valve (IACV), if it does I would be looking at that first, i.e. disconnect completely and restart the car and see how it behaves.
