Ok, so about a week age i was going down the road, and the motor started too feel like it was loping and it was losing power. The CEL light would flash anytime i put a load on it. It felt like it was missing. I took it to Autozone, to get it checked, and it said that i had a cylnder 2 & 4 missfire.

Today i got to work on the truck(yay!), checked all the plugs, fine. So i went to Napa and bought a new brass cap, rotor, and coil(they were prolly about to go any way). I got them all put in, started the truck and it didnt lope anymore. Went down the road to see if it would come back(missing), and it didnt. The truck acually had a LOT more power than before, it did a pretty sweet spin-out when i got on it, too! I went back home, and as soon as I pulled into my driveway, it started to miss again! F@CK, I was so PISSED!!!!!

So, what know?
Cracked head?
Plenum Blown?
Bad Injectors?
IDK?

The truck has never smoked(anything but tires!). The plenum doesnt look all that bad, but like i said before, it has never smoked before and ran great before this $hit popped up. This truck is eaisly the best vehicle my dad has ever owned, but im afraid that it might start taking dumps on us.

It has 169,000 miles on her. With a 318
Thanks guys

 

do you know anyone with that same truck and motor if so swap the coil and see the coil could be going thats a way to check before you spend the money

 

i would worry about the heads. Thats the same places I had misfires

 

yea thats truck get them checked. if one is bad look for a cylinder head exchange place where you can take yours in and they give you some ready to bolt on for a $100 or so we have one here but i dont know about anywhere else.

 

I already spent the money on a new coil.

 

When the guy at Autozone said i had a misfire, first thing i thought was about you truck.

 

ok well what ruels that out!! and you changed the rotor cao and button? what exactly is your truck doing... like go through the steps

 

Tomarrow I am going to have a guy do a compression test, and check the plug wires.

 

I can have a video tomorrow or friday.

 

pull your cap off and look under it and see if there are any black lines under it like where the spark is skipping from one spot to another it will look like a burned black line.
