CHECK ENGINE LIGHT SHOWING ON DASHBOARD

Chevrolet Impala
P0172 is indicative of Bank 1 running too rich (receiving too much fuel) on V-type engines or high performance inline engines. It causes the check engine light to illuminate, but beyond that, the car runs and drives as it should, often times with no noticeable difference in performance. Possible causes could be, but are not limited to, dirty or faulted Mass Air Flow sensor, dirty injectors, clogged PCV valve or hose, or damaged vacuum line.


when i start the truck it idles roughly then check engine light comes up giving me a PO170 bank 1 to rich.

Engine light on when the car put in reverse, it make a loud noise as soon as you release the brakes pedal. Also in drive only when the car completely stop at the traffic light, as soon you release the brakes pedal again the car launched forward with a jerking motion, after initial move everything is smooth when the car already in motion.
