Where to look? Short post due to forum problem _____________________________ 2000 Accord V6 CDN.4 dr auto 1984 Honda Goldwing Post #: 1

The ECU threw a P0304(#4 misfire, and the CEL blinks during the misfiring-according to the owner) It really vibrates at a feathered throttle, but runs strong and smooth upon acceleration. It is getting new wires, dist cap and button today, but I doubt that is the fix. Could it be the tranny(torque lockup) Will report back. _____________________________ 2000 Accord V6 CDN.4 dr auto 1984 Honda Goldwing (in reply to Hondaccord) Post #: 2

After new plugs, leads, dist cap and buttonthe missing under light load is still there. But that should eliminate the misfire code eventually. Best method of cleaning the injectors?????????  Thanks _____________________________ 2000 Accord V6 CDN.4 dr auto 1984 Honda Goldwing (in reply to trukid21) Post #: 5

This might cause a lean miss. If that doesn''t show anything, suggest swapping injectors to see if problem follows injector. If yes, I would get a used replacement. good luck _____________________________ See you down the ROW 1994 Accord EX (in reply to trukid21) Post #: 7
