1999 RANGER 3.0 AUTOMATIC FLEXFUEL 4X4
RUNNING E-85 BIOFUEL (SINCE AVAILABLE) LAST YEAR. RUNS GOOD (EXCEPT FOR BELOW 20 F:
HARD START). SUDDENLY RUNNING EXTREMELY ROUGH. THOUGHT 'BAD GAS' & RAN ALMOST DRY & PUT HALF TANK OF 94 OCTANE. BETTER FOR A FEW MILES THEN RUN ROUGH.
SNAP ON SCAN TOOL INCONCLUSIVE-NOT TALKING TO COMPUTER.

ANY IDEAS?

PLUGS 4, 5 & 6 SLIGHTLY FOULING AFTER 200 MILES
PLUGS 1,2 & 3 ARE FINE

COMPRESSION APPEARS TO BE FINE IN ALL 6 CYLINDERS: BETWEEN
140 & 155 LBS

HAS A STEADY 17" O F VACUUM WITH NO FLUCTUATION ON THE NEEDLE AT ALL

Check for vacum leaks, also check the PVC tubing. I had a issue with my 03 ranger edge runing rought and it sounds like similar problems, But mine was able to talk to a scanner. turned out that the PVC tubing on mine was cracked.
