I will be getting one of the newer Chilton's soon.
Anyhow, I think I figured out how to pull the codes and all I am getting is code 55. My problem is I can't figure out how to get it out of the diagnostic mode - when I start the car and let it run for a few minutes the check engine light begins flashing, blink pause blink blink pause blink blink blink pause etc until it flashes five times then it starts over.
How do I stop this - disconnect the battery? or is there a way to do it at the computer?
Nonetheless I am still no closer to fixing my stalling problem. The car keeps wanting to die when I come to a stop unless I feather the gas, if I am sitting in the driveway and rev it up sometimes it will idle way down and stall out.
Car is a 1989 Sentra, 4 sp base model - California emissions - bought the car new in Jun 89, car has about 222,000 miles on it. Things I have done so far - new fuel filter, air cleaner, vacuum hoses, O2 sensor, PCV, NGK plugs, wires, cap, rotor, new alt in 03/05, new timing chain, guides and tensioner 08/05. Timing is in spec, Cat was new about 3 years ago.
I did spray down the butterfly and the screen on the idle air passage with some sensor safe throttle body cleaner - didn't seem to help much but it did clean up the looks of things.
