I keep getting coded P1130, 1150,1152,0172 & 0175 which tells me that the engine is running way to rich. The gas mileage is around 13 mpg which is much lower than my 1999 vulcan. The car is a 1996 Taurus LX wagon with the Duratec engine. It is so rich that it soots up the rear bumper. I replaced the upstream O2 sensors and the spark plugs. Also is there a good shop manual that has a trouble shooting chart. I bought a Ford CD on Ebay but it really does not have a good trouble shooting section. I was looking on Ebay and see a Ford manual in a binder anyone have one of these. Any help will be appreciated.
