Hi, I have Infiniti FX 45, 2004 Model. Once when I accelerate on cruse control mode it immediately stopped and within few seconds it started again, this happened while car was running at 100 kmh. I thought it had something to do with Cruse control but actually not. Later I used fuel tank cleaner and for some days problem didn't happened but later started again. Can you please suggest what should I do.Thanks.

. Check for codes.

. Consider replacing the Crankshaft Position Sensor and the Camshaft Position Sensor.

. Replace the spark plugs with the same NGK plugs that came in the car, if they have over 50,000 miles on them.
