2003 V6 - One cylinder is mis-firing - Why?
My 2003 EX has 165K miles and runs like a champ - until yesterday. Leaving work, it started runninig very roughly so I drove straight to the dealer. They confirmed one cyluinder was mis-firing but after 3 hours of diagnostics and a top-end decarbonizing tretament they still can't figure out why. They swapped plugs, coils, spark plugs, etc. and this one cylinder still mis-fires. I forgot to ask if they tried the wires. I assume the diagnotics would verify the computer is not the problem. Any new ideas?
