Try a TPS check/adjustment first...

How's the timing?

Well the ACV is to help prevent backfires... so if you removed it... well

And why have you not checked for a vac leak with some spray starting fluid??? (you spray it around the intake, and when it finds leaks in the intake system, the RPMs go up).
