by revved up… you mean warmed up?

I had this problem with a bad EGI relay = fuel pump control. Drove fine, but the idle would bog the car out.

Try cleaning your maf and iacv…best solution i can think of atm

It could also possibly be a vacuum leak.

if you are venting to the atmosphere then thats more than likely your problem., Plumb your BOV to your intake and it will be all good.
