1994 Ford F150 V8 Two Wheel Drive Automatic 115k miles
Check engine light flashes 4 times within 30 seconds of cold startup. Engine rpm advances about 500 to a 1000 rpms within about 10 to 20 seconds of flashing. Engine rpm drops to stalling speed about 10 to 20 seconds after that and sometimes does stall, but usually picks back up to to hi idle and settles to idle. Engine runs fine for rest of operating cycle. Repeats each operating cycle at cold startup. All sensors tested or replaced. Have been opening and cleaning electrical connectors. KEY ON ENGINE OFF OBD 1 PROCEDURE SHOWS NO CODES EXCEPT 111( SYSTEM PASS). Anyone have any experience with this or any ideas?
have the same problem?
