I have had a problem 3 times with my LBZ and need to know if anyone else has seen it. All times have been under some load with the engine warm. I will be driving and try to accelerate the truck blows black smoke and knocks. I am not talking about a little spurt of smoke, I am talking about a lot. Enough that the mechanic at the dealership noticed it in the pipe. When I say knock i dont mean like having bad fuel on a 4 cylinder engine. I mean it woke up a person sleeping in the truck.
I am not getting a code with this so the dealership has no idea what to fix. They said try fuel additive.
Also, when i am driving 65 and push my foot to the floor it takes 3 seconds to actually move the speedometer. My dad has an 02 and it takes off almost immediately. Again, no code so no fix.
I want to get this truck problem corrected so I can start adding stuff like aux. fuel tank and programmer but I dont want to do anything to the truck while it is having problems. It only has 6500 miles.
