Slow city driving in the rain today when, with no warning or mishap,
the "Service Engine Soon" light came on.  No symptoms, car runs fine.
Tried the ignition key on-off-on-off-on trick and got the "Service
Engine Soon" light to blink out codes: 12 43 55.  Alpar.com interprets
this as two codes, 12 and 43 with 55 as "end of codes" delineator.
The 12 code is: "Battery or Computer recently disconnected"
The 43 code is: "Peak primary coil current not achieved with max dwell
time...OR...Cylinder misfire...OR...Problem with power module to logic
module interface"
Yikes!
A few days ago I had a mechanic repair a slight leak of transmission
fluid at the radiator connection... perhaps he disconnected the battery
as a safety measure before doing the work.  But the other items??
Anybody have any idea how I could differentiate among the three
possibilitiues for code 43?
Also, is there a way to reset the system so that the "Service Engine
Soon" light will go out?
Thanks.
