96 ranger xlt 3.0L automatic 135K miles....
I basically got it for peanuts...
it looked like crap, but all it needed was a good clean up, since it have been sitting in a car port for 4 years plus with out ever being driven....

I put some air in the tires, new battery and fresh gas in tank....
fired her up, it took a few cranking sessions...
I ran like crap at first,shut it down...restarted and ran great....
after 5min service engine light came on...
scanned and got a P0102 obd2 code (Mass Air Flow (MAF) Circuit Low Input)

I have replaced maf sensor and that cleared the trouble code....
gave it a full tune-up..
oil change, new plugs, wires, air filter...
oxygen sensors, 2 new upstream and 1 downstream....

erased codes....

now it's 400 plus miles later...
and scanner still reading P1000 code
all readiness monitoring has been established , except catalyst
the C has been flashing for the last 200 miles and is the last sensor that have to clear emissions sensor readiness check....

scan tool im using is a INNOVA 3000f

if been following these instructions....
Ford Motor Company Driving Cycle

I was expecting I/M monitoring status ,would have completed by now....
am I being to impatient or ????? is there something else holding this process up....
im in California and wont be able smog and register until everything comes into check..:bicker:
truck runs fantastic or as good as expected from a 3.0L and i'm not getting any trouble codes ,except P1000
any ideas...

Cool deal. usually its the evap that takes the longest to pass. typically what I would do is drive the truck from cold start up till warm on city streets and then 10-20 open highway miles, fuel level needs to be between the quarter marks the entire time. should only take one or two times at most to clear all monitors. BUT some cars are way more stubborn than others though..
