86,000 miles and my engine started surging. Engine light on/off
What is your question?
Had timing chain repair job 10,000 miles ago now at 86,000 miles. Tonight while driving to work noticed it's getting over 21 mpg in the city (normally 15). Cruise control on engine starts surging when I was on the interstate. Turned cc off engine still surging. It would not accelerate properly. Drove it back home and engine light comes on and off but never stays on. I did turn the vehicle off and restarted it before returning home. Surging/cutting out at all speeds all the way home. 4 engine codes P0300 p/d, P0131 p/d, P0151 p/d, P062B p/d. Any ideas?
RepairPal Certified shops can diagnose and repair your 2011 INFINITI QX56. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
P0300 is random misfire , P0131 is A/F or the airflow sensor for Bank 1, and Po151 is for Bank 2, with P0300 which is a random misfire you can expect the A/F sensor which is referred to as the 02 sensor to code up, the problem you have is with 062B which is for the ECM injector driver unit malfunction. Have the connection of the injector check for proper connection. With also the charging system , at idle should be 14 to 14.5 volts, The worse scenario would be a ECM replacement.
The only consistant code that keeps coming up is P062B. All the voltages are correct and connections are fine. I'm at 92000 and put in new plugs. Still get the code popping up every few days.
