1997 BMW M3. HAS CODES OF P1421 AND P1423. CAR SEEMS TO RUN OK, BUT HAS A FEW PROBLEMS STARTING. CRANKS FINE, BUT WILL REQUIRE CRANKING FOR A WHILE. NEW BOSCH PLUGS. NO OTHER CODES OR PROBLEMS. OWNER RECENLTY HAD ENGINE DETAILED, AND I ANTICIPATE WE WILL FIND A WIRING PROBLEM/SHORT. ANY INSIGHT WOULD BE HELPFUL.....WAP
