New to me...has a miss

[Brains646]

Your not messing around.

Nope!!

I got this truck for next to nothing because of these little issues. I'll admit that I've always been a Ford SUV man but I quietly envied my Chevy brothers ease of repair. I'll have everything except the ball joints done by Monday. My wife will be driving the truck for a few weeks so I need it tight and right.

Thanks for that info, I plan on digging into the rear blower this weekend or next.

I've got the two injectors on the way and I'll have that done tonight. I also ordered a light switch and all three actuators/motors for the climate control as well as two upper ball joints and the fuel vapor release cannister. All these should be getting installed thise weekend. Hopefully by Saturday night I'll have control over the vents, lights on the dash and a smooth running truck!

Dayuuuuuummmmm! I hope to not need all that. The truck is eventually going to my son but until them its the wifes/house truck. She only drives about 10-15 miles a week so its all good. She was so disgusted by our Armada eating up its rear end that she said to get this one, sell that one and she'll wait till she's ready to get the suburban she wants.

It must be doing something because if i unplug it the truck stops. Everything works correctly with the cooling system. i checked the plugs and seems that one is getting good spark but the other had carbon on it

It may be functional...but it is definitely broken. That blue grommet on the connector shouldn't be showing, it should be inside the black part showing in this image. Yours is missing that bit.. Should look like this:

I got 229000 miles on it so it's understandable I needed to rebuild most of her.

Your oil on the plug means valve seals or bad rings. The "miss" could be the case of bad compression in that hole or fouling of the plug.

Compression checked out fine, the source of the miss is two injectors that are stuck open. The oil is coming from the valve cover gasket that needs to be changed.

Oh lol the oil is on the ceramic and the plug boot? Sorry

Pulled the injectors and saw this inside. WTH?
