I just had a problem with my Crysler LeBaron.  I have the manuals
and they say that if you turn the key on/off/on/off/on in 5 seconds
it will flash the error code.  Sure enough, it flashed a 51 and
a 55.  The 55 is end of message, the 51 is for oxegen circut stuck
on lean.  I repalaced the O2 sensor and it runs fine.  The dealer
wanted $35 to diagnose it.  My manual also talks about hooking
up a device to exercise various functions.  Does anybody have
information on if/how one might do this with a pc?  They
want $1000 for a hand held terminal.
