I have a random misfire code p0300 on my 98 chevy truck. I have replaced plugs, wires, cap, and rotor. Also replaced the MAF, i have troubleshot it down to the possible spider injection system failing. I removed the throttle body assembly and saw there is excessive sludge and what looks like fuel on the intake manifold. Im really running out of ideas and dont want to throw parts at it constantly til it runs right.
