Recently fixed cylinder1 misfire. Still showing P0171 & P0174 codes.How do I fix this?
MY 2001 FORD TAURUS 24 VALVE DOHC IDLE ROUGH WHEN STOPPING AND ON THE BRAKE WITH CAR IN DRIVE IT WILL STALL. BUT WILL CRANK BACK UP. WHAT COULD BE THE PROBLEMS?
Start with pulling any check engine light codes and then post them below in the comments for further information. Could be a failing engine sensor or ignition component accompanied with a sticking IAC valve. These will cause the engine to idle rough.
