Hi all!! My 90 New Yorker 3.3L is showing a code 43. The decode page shows more than one cause pertaining to either iginition coil, or cylinder misfiring. The car seems to start and run fine. Spark plugs and wires are about a year old. What would be the main cause for this code? Does it mean I have a bad coil? Are there any other symptoms I should look for or any diagnostics I could perform? Thanks in advance!! Dennis sed55ATTyahooDOTTcom
