2004 Misfire
 

So heres my problem. Three days ago i was driving my truck on some pretty flooded roads, and now my truck is running on 5 cylinders. What do you guys think could be the problem?

Thanks for any advice in advance.

figure out which hole is out first....the old fashioned plug-unplug method should still work on these motors?

you probably fried a coil pack or an injector wire. try figuring out which cyl is misfiring by using process of elimination with unplugging injector wires. once you find it, pull the spark plug. if it's wet and has gas on it that means its getting fuel but no spark. in that case i'd say its a coil pack. if it doesnt have fuel on it, then its probably an injector problem.

no codes i assume?

oh no there is deffinetly codes. its a solid code when it stops doing it, but then when it starts missing again it is flashing just like a misfire code. so, im kinda at a loss right now to figure it out.

i just went to advance so they could plug into it and it says it is a cylinder 5 misfire.

like wink and I said, pull the plug and see what it looks like.
