Any input? When I first start up the car it idles high. At about 1500-1700 rpm. It idles there for a minute or two and then it drops down to about 500-600 rpm which seems low as it runs on the rough side. Any thoughts or suggestions are welcome. Thanks!

Throttle body?...any check engine lights? Try cleaning your throttle body...it could also possibly be bad coil packs

No engine light and I just changed a coil

Possibly vacume leak from the brake booster towards the back of the engine...I had similar problem with my v8 awd hose got loose
