I have been chasing a persistant CE issue for 6 months. If anyone knows a fix that works PLEASE help.
Ford Explorer Sport Trak 2wd 2001 4.0L SOHC V6 140,000 miles
What I've tried so far in sequence of repair:
-all 3 O2 sensors
-Sensor on Right Valve Cover[2 vac lines]
-proffessional Power Clean Injectors
-PCV valve assembly [w/3 VAC hoses]
-Replaced both O-ring sets in Intake/throttle Body
Until I replaced the MAF sensor the Check Engine light would come back on in approx 50-100miles after replacing MAF Sensor it comes back after erase in about 15-40 miles.
