What truck do you have year and engine to

 

you probably have water where it doesnt belong. let it dry out and if it doesnt get better than pull the cap and check for mositure in there. if there is, then dry it out and re-check it. if you do nothing and let it run and it runs better, then check your wires. you might have some bad wires causing a miss fire to the block.

 

Bingo...
was no seal at bottom od dist...
musta gotten wet...
was gonna replace with accel....ahead of schedule now that I know it can't be trusted...
thx

 

That would make sense.

0300 Engine misfire
0302 Misfire cylinder 2
0304 Misfire cylinder 4

 

Heres a good reference site for you guys

po300 is a random misfire code 302 is cylinder 2 and po 304 is cylinder 4 not an o2 sensor you need to clear the water out of the plugs
