I used to have similar problem, due to a leakage at the air-filter box, where the vacuum hose connects to the air-box. In my case, the vacuum hose connector (PVC one) cracked, probably due to the mechanic accidentally pressed on it when servicing my air-cond. Can try check vacuum hose leakage too.

Hope this helps
