getting a stuttering on acceleration?

[WyoDenali]

my 04 Denali is stuttering om acceleration for a stop. I have gotten the code 300 random miss fire. I have checked that thee plug wires where all attached properly.
Anyone have another possible cause and correction for this problem???

thanks

Could be incorrect gapping on your plugs and also make sure you put the dielectric grease on your boots

Also our trucks use a special plug so make sure they are the iridium ones

Your wires could be toast, it doesn't matter if they attached properly or not. If they're old just replace them. Also your plugs could be done. All depends how old they are I guess. I replaced my plugs and wires not too long ago with ngk platinum and my truck is a lot happier now. Also make sure to put dielectric grease in the plugs

Im using tr55s >.>
Check the fuel filter if you got one mine never got changed @200k and when i pulled it the shaking from the motor stopped when disconnected it black sand looking stuff came out only regret is it consumes more fuel now
Also try cleaning the maf and throttle body

tune ups make a world of difference

It seems to be worse when it is cold.
