P-0304 indicates number 4 cylinder misfire. Are you using Toyota parts dept spark plugs? More often than not, non-toyota plugs make the v-6s run poor, right out of the box....
Try this:With the engine running, pull the connector wire off of the #4 injector. Note to see if there is any change with the idle quality. No change? You may have a bad injector.

02 Toyota Tacoma when engine warms up cylinder 3 has a misfire po303


check spark plug of the cyl. switch plug with another cyl, run engine until warm to see if misfire still comes on. if it stays on the same cyl. fault could be high tension wire or coil or worse leaky valve or rings. if misfire switched to the other cyl just change plug or better replace all plugs

I was having the same problem changed plugs, plug wires, coil packs, cat converter and had injectors flushed....cost quite a bit and nothing fixed the problem.

OBDII code P0306 describes misfire # 6 cyl or ign misfire, wires are new, coils (3) are new, rough idle on acceleration possible bad fuel injector or ???


I noticed that you didn' t mention the plugs. I'll assume that if you did wires and coils that plugs are also new, so I would say that you need to check the injector on that cylinder

Code 304 won't clear new plug wirea,new coils 2002 4cyl sanoma


Code 304 is a cylinder #4 misfire. After changing plugs did you clear your code by removing the negative battery terminal for a few moments and then re-connect. Also if the code returns check your cyl #4 wire for degradtion.
