Truck started like normal this morning and I drove about a half mile normally then I went to accelerate up a hill and she will run fine up to 1200 rpm then lots of black smoke even with the pedal to the floor no more than 1200 and it does it in park or drive I limped it back home I just have no idea what would cause it to act like this

 

you always start with the fuel filter

 

Check your air filter too, after your fuel filter.

 

Fuel filter has 4000 miles on it and air filter was cleaned this weekend

 

Black smoke is running rich. It more than likely can't breathe or it has an injector or two stuck open.

Is it a turbocharged truck? Does it have a cat?

 

I found the problem the metal cap on the aftermarket cone filter came off and was grinding on my turbo restricting the air any recommendations on ones that will hold up this one is 3 months old it is a spectre

 

When you said "cleaned" the air filter, I got a sneaking suspicion it had some cheapo aftermarket filter. They're all known for letting in too little air, too much dirt. If you have a tubular intake tract into the turbo, you need a NAPA 6637 or the Donaldson equivalent (I forget the number).

 

Well from the looks of it that won't work here is why



Out of the truck

 

 

That is sch 10 3" pipe

 

get a 3-4 inch adapter, a 90 degree elbow and a 6637 filter.
