Wife's came home last weekend and engine had a rough idle. I scanned the motor KOEO and pulled a Code 157 MAF sensor. I replaced the MAF sensor and the code went away. Ran a scan KOEO & KOER and pulled no codes. Rough idle continues, so I inspect IAC which was replaced a couple of years ago. Valve looks sticky, but working. Replaced with Motorcraft IAC. Today, I decided to drive the EX to work. The idle smooths out over 1800 RPMs, although I felt a slight shudder while cruising at 70 mph. When I returned home I noticed excessive fuel consumption. Third of a tank for 70 miles. Now, I suspect Fuel Pressure Regulator or Fuel Injectors. I have ruled out head gasket, car ran cool the whole ride on a 103 degree day in Southern CAL. Besides the intake gaskets, what else could cause this condition? I replaced the DPFE sensor about fifty thousand miles ago with Ford upgrade.
