The first thing that i would do is check your cap and rotor for corrosion. look on the inside of the cap and see if there is corrosion on the tips where the rotor sends electricity to. check the tip of your rotor button for wear and corrosion on the tip of the rotor. If thats all good make sure wires are not bad by purchasing a spark tester at your local parts store. Its only a few bucks and you hook it on to the spark plug end of the wire and it will spark if the wire is good. If they are good then check and make sure plugs arent fouled out and make sure the gap between the electrode and the tip is correct. About .045 is usually the spec for them. then if that is all good i would consider replacing the coil because if the coil has a short in it, it could possibly cause a random misfire.

2000 GMC Sierra w/4.3 misfire on #2,4 cylinders


If it were low fuel pressure misfire , it wouldn't be cylinder specific misfire #2 , 4 it would be P0300 random misfire . I would think fuel injector's too . When hot they could be breaking down electrically , more resistance . If they tested electrically with a lab scope they would know for sure . Misfire from sticking fuel injector no fuel misfire

Before you replace the injectors have them do an injector balance test. Normally wet weather does not effect fuel system. Sounds more like you have a crank or cam sensor acting up.

Need some more info on some diagnostic codes that came up on my truck & how to fix them. P0137 o2 sensor, P0300 random multi miss, P0303 cylinder 3, P0306 cylinder 6, P0307 cylinder 7


Replace your O2 Sensor and Spark Plug Wires. If you still have the Random Misfire, replace your Spark Plugs, then Replace your Distributor Cap and Rotor. If you still have the Random Misfire you may have a Timing Problem, or Ignition Coil problem.

Engine misfiring.


most all v8's have the same firing order which is 1,8,4,3,6,5,7,2. sparkplug gap seems fine. with the engine off, bend the sparkplug wires between your fingers, if small cracks appear then replace them. number one sparkplug is located at the front driver side of the engine, front to back on this side are cylinders 2,4,6, and 8 respectively. turn the engine to the compression stroke on number one, pull the cap, the rotor points where number one will be.

What do these trouble codes mean po306 cyclinder misfire detected .how do i fix the problem?


it means you have a misfire on the number 6 cylinder

this could be caused by a whole lot of reasons.

start by inspecting for a bad plug wire if it has them

check for fire on the cylinder with a spark test tool from local part store

if it is a coil-on-plug set-up, check the coil for fire

replace coil/plug wire as needed, replace boot on coil if coil needed, replace spark plugs
