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.

A cylinder misfire occurred. How many miles on this vehicle and when was the last tune up done with a good set of plug wires? The check engine lite will go out after the problem has been fixed/or if it doesn't occur again after the monitors have passed.

Hi:
I had similar problem on my 98 Plymouth voyage a month ago. First, I replaced spark plug, it corrected problem some what. Then I replaced all the spark plug wires. The problem is totally gone. Try that first and see if it will go away.
