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
Id check for vacumn leaks first,check the fuel pressure should be around 45 lbs ,check and replace your plugs ,don't forget the fuel filter
