I was sitting idling long after the engine warmed up, and I noticed the RPMs went from 700 idle, and began to dip a little to 500, and then went right back up. Nothing much happened, but this could be a future problem..

 

mine does this also ?

i just assume its normal it doesnt do it after its been driving tho just when she is freshly started up

 

Idk if these cars have an idle air control unit but that might be something to check. WAit. Nvm they would prolly be revving a lot more than that.
