p0300

Hello peps.

So a month a half ago the truck was stumbling a tad and then a injector went down.

Having found the dead injector and replaced it truck of course ran much better.

But. at low rpm, not at idle but between 1600 and 2100 it will tend to misfire not enough to light the CEL. so, if you are cruising along at street speeds it will stumble slightly. Not when you apply gas only if you are being gentle with it.

when I pull codes even without a CEL I get a p0300 which is random misfire. which is not very helpful.

Id like to fix the problem before it strands me somewhere. and I dont really like waiting for it to really break for me to find the problem.

When is the last time you did the typical maintenance stuff- Plugs and wires specifically?

The plugs were replaced less then a month ago. the wires i dont know. did not think about the wire since i could get a 2 inch blue spark from the plug to the firewall.
