asked by on March 11, 2017

The car is hesitating into 3rd and sometimes 4th gear. Sometimes when slowing it accelerates. Im pulling codes PO 171, 140, 121, and 101. Please advise. I don't want to damage the engine or transmission, but I'm unemployed and I don't have many options.

My car has 98000 miles.
My car has an automatic transmission.
