Hi , i have a 1995 Escort with 1.9 4 cyl engine , at cold start the engine revs ok but as it get warmer it start to idle rought and die , with a scantool the o2 sensor always reed lean at idle , after checking fuel pressure , air mass meter , EGR valve , and potential vacuum leak at intake and hoses , its the PCV valve that give me that problem , as i remove the pipe with the valve there was a whissle noise comming from it , when i block the valve at its tip the whissle noise stop the engine revs smooter and the o2 reads normal , i replace the PCV and its idling good .

My 2002 Ford Escape had exactly the same problem as described. Dealer replace oil pressure sending unit (oil pressure switch) and problem still existed while leaving dealer about 3 miles away. I took the car back to the dealer again in two days and the oil pressure light kept of blinking sporatically all the way to the dealer. Dealer checked connections and they drove the car around and the oil pressure light never came on. I picked the car up from the dealer and I've had no problems with the oil pressure light flashing. I wonder if there is a microprocesser in the oil pressure sending unit which has to be given some time to be recalibrated to the cars main computer module?

There could be many issues. These codes read your engine is running too lean. Check : all your vacuum hoses for leaks, PCV valve and hose, MAF sensor. This may require an experienced technician to figure this out. Hopefully I help'd!!
