Taurus 1995 3.0
Hi I'm having trouble with my Taurus. it is not an SHO. it is running rich and i ran it through a ford code scanner. it came up with the codes 159-MAF sensor signal voltage is higher or lower than expected. 121 TP sensor- signal voltage inconsistent with engine intake air flow.335-EGR (PFE) sensor or EPT signal voltage higher or lower than expected. 543- Fuel Pump circuit open connection- Electronic Control Assembly to battery. the car is running lousy. stalling at traffic lights, black smoke out the exhaust. i put in a new EGR valve and a used MAF sensor and still get these 4 codes. should i install a new MAF sensor or is one thing causing the other ones to show up. need some help . thanks SkyDog
