1990 Ford Bronco
5.0l; (California)
5-speed manual
Historically, has always run well and started immediately. I let it sit for
about 6 months, and then wouldn\\'t start (battery good). Got it started, but
has run rough ever since.
Trouble codes pulled: KOEO = 11; KOER = 21-41-73-25
-Added 3/4 tank fresh fuel to 1/4 old fuel
-Two doses of fuel system cleaner in tank (because 32 gallon tank)
Replaced:
-Spark and coil wires
-DIstributor cap & rotor
-Iginition Coil
-Spark plugs
-Oxygen sensor
-Fuel filter (on-the-frame)
-Changed oil & filter
-Cleaned air filter
-Cleaned throttle body
Cleared computer codes, now returns only: KOEO = 11; KOER = 41
Still runs rough at idle, low rpm and hesitates (misses) at low rpm upon
acceleration. |
