Code P0300

[DOPEITSDT]

Replaced broken 2 burnt coils, did the sparks plugs were first gapped at .32 then regapped them at .28 and still running like a bag of dicks. Starts shaking with little throttle but at half way it's not bad at all but full throttle it shakes bad too. Can't figure out what else it can be help ?

What's your fuel trims look like?

300 is random, could be a massive vacuum leak.

A leak to cause what you're having would be on the intake manifold side of the TB.

My valve cover is leaking on the passenger side would that cause any problems?

How old are your ICMs?
Seems like the 0300 misfire is usually ICM related... as opposed to a bad coil/plug which usually throws a specific cylinder code.

Were those new plugs you put in or did you just re-gap the old plugs?
