Asked by Hari Jan 17, 2020 at 04:40 PM about the 2013 Honda Odyssey EX-L FWD with DVD
Question type: Maintenance & Repair
I drive a 2013 EXL Odyssey with 110k miles 80% of mile are highway long
distances , well maintained by dealer until 100k.
few months back there was CEL with P0303 code, mechanics (not the
dealer) suggest 3 rd spark plug bad and suggested i change
it and as perhis recomendation changed all 6, drove about 100 miles again
CEL came up
and also this time lost power and felt shaking when hit the gas pedal.
Went to mechanicagain the same codes came up, so he suggested 3rd
coil need to replaced,
got it changed and drove straight 100 miles , the CEL came up again and
same shaking for some time .
Took it to different mechanic(maineke), this time they found same code but
after hearing the story they
suggested a deepdiagonostic like the cyclinder pressure test etc, and
confirmed there is noissue,
but noticed the 3 spark plug is burnt , however said there is no oil leak issue
which might causeed it and said might be the defective plug
so changed 3 rd spark plug. ( till now spent 450$) and sent me home. I drove
about 30 mil at a stretch so the light did not come back yet
but , however i noticed the the Gear shift and around it in the cabin seems to
have warmed up ( probably will get hot if i drive more ,
not sure), so experts please share your knowledge , i am guessing it could
be EGR or computer software, solinoid issue in transmission in turn is
creating this mess with the 3rd cyclinder missfire, any suggestions welcome,
scared to take to mechanic again because they are just doing the
routine check and not pinpointing the issue and fix.
