Guide : : Car is jerking back and forth. P0171 and P0172 codes are on.

Car is jerking back and forth. P0171 and P0172 codes are on.

Car runs like normal but after a while will begin to struggle jerk back and forth and won't accelerate if I hit the gas pedal then will go and shut off on me and won't turn back on until after a couple of minutes. Car does it every now and then at random times shows the check engine light and shows both codes p0171 and p0172. My car has 170000 miles. My car has an automatic transmission.
