Hello, cel came on a few days ago. Had the codes pulled and came back with those three. Engine running rough and also stumbles when accelerating from a stop nearly stalling. There of course a noticeable loss in power. There are 66k miles on the vehicle and I'm wondering if I should start with the plugs or someplace else? Thanks
Codes are po600, Po603 and p0606. Nothing done recently other than oil change and new air filter. Code description I found was random misfire. Thanks for reply
Posted wrong codes previously. There are 66k miles on the vehicle and I'm hoping it just needs plugs. Do plugs go bad with this low of mileage. I assumed the OEM plugs were guaranteed for 100K miles? Should I start with the plugs?
Two threads merged into one, updated title.
the p060x codes are ECM ..... misfire codes are p030x SO I suggest you recheck and repost codes.. BIG confusion
kev2, the codes were actually P0300, P0303, and P0306, I updated the title to correct that now.
these are computer codes.... errors in the vehicle PCM... not exactly a spark plug issue.... any thing reciently done to vehicle? some history? Otherwise a professional technician, preferable a shop specializing in honda .
