Having problems with your Ford Contour ?

P0174 and rough idle 6 cy 96 contour

\015 I cleaned EGR passageway to throttle body it was really clogged now I have a P0174 and a P0171 pending . cleared DTC's but they came back within 10 miles of driving. I do have a vacuum leak going to the heater A/C system since I only have defrost when I turn on the heater not floor or panel vents. I replaced the upper body intake manifold gasket. I can't hear any air leaks. My idle bounces between 600 and 800 RPM when stopped at a light. Car runs great even at 250,000 miles.\015 Posted / edited by AnonymousUser on : 26-10-2020
