This all started with a distributor change due to broken cap screw. I bought a loaded aftermarket distributor. When I put that in and took truck to dealer for fuel sync adj it ran like crap. I brought truck home and swapped aftermarket cam sensor with factory one and truck ran much better but still seemed a bit sluggish. I drove it all around and plowed a full season all seamed ok. Then my factory cat broke into pieces. I replaced the cat with a new aftermarket and all was good but still seemed sluggish. I did the plenum, tune up ect, no help....Then it hit me that I did not ck fuel sync after I put factory cam sensor back in, I ck in with my local shops Snap-On scan tool and sync was 23 not 0...I set to plus 5 drove it ran a ton better but still no go under heavy load. Reset to 0 the other day still no improvement. Installed new cat today truck runs like a raped ape.
