I occassionally have engine hestitation, especially when I slow down at a traffic and about to pedal down to move again the engine rpm drops & I have to off the engine and restart several times before the engine picks up on good rpm to move again. Tried cleaning the Airflow sensor but no success. The system diagnosis reads the following;
1. PO420; Catalyst System Efficiency Below Threshold (Blank 1)
2. P0657; Actuator Supply Voltage Circuit/Open
3. P2116; Throttle Actuator control motor Current Range/Performance
have the same problem?
