We drove it around the block a few times & I wonder if there is not something even worst happening right now. When you put the pedal to the floor it has almost no power. My IDI can whoop on it all day long. It has some kind of unknown free flow muffler with a 5" side can welded to it. But I don't think that's the issue here. When you start it up it puts out a little puff of white smoke. So I'm thinking the HPOP is starting to go weak.:shrug: The guy had a chip in it before, he didn't know what kind but said he didn't like it & pulled it out. I think at 170,000+ miles as a everyday work truck & plow truck the motor is just getting tired too.
Any input on this would be great.
