I did the key dance because my CEL came on the other day and it gave me the code 43. What is there to do to trouble shoot this problem? I recently have changed my plugs from NGK BKR6E-11 to the 5E-11. I changed them Fri. and the CEL came on Sun. Any suggestions welcomed.

Ok since you jsut changed plugs Im guessing you dont have a secure connection from the spark plug boot to the plug or even it might have come loose at the coil pack, I would make sure all the connections through the spark plug wires are secure and then disconnect the battery to clear the CEL,
But in the future the keydance is only a starter thing to do code 43 is a general misfire, if you get the real codes from a scanner (autozone does it for free) it will tell you the P0301-303 codes which are much better at determining the problem see below what 43 means 43 means all of those but you see the "P" code tells you exactly which cylinder,etc...
