any vacuum leaks? any over revs? bent valves? do a cylinder leakage test, or take it to the mechanic and have them do the test?

[wnt_2b_boosted]

how hard is the leakdown test?? can get a tester at harbor freight 4 like $50.and y would the problem start after i cleaned the iac.

No over revs, no vac leaks, was fine until cleaned out the valve.
