2018 Honda Odyssey Misfiring
 

My 2018 Honda Odyssey just started misfiring. There is no code. My mechanic determined it is Cylinders 3 and 6. But he can't figure out what is causing it. Any suggestions? Anyone with the same issues? I have had so many issues with this model.

Did the mechanic check the misfire counter on his OBDII scanner?
Causes for misfire can be coil over plugs are faulty
Or, bad fuel, faulty fuel injectors, bad valves, bad head gasket, poor grounds, large gap spark plugs.
Figuring out the misfire requires a bunch of testing
And on a 6 cylinder engine, it is tough to access all the spark plugs or injectors\
Lot of work for diagnostics and very little money.
So some mechanics will just throw up their arms and pass.
