Well I checked a few things out this morning I warmed the truck up and pulled the plugs all look normal the gap is around .032 which is normal stock is .031.
I then did a compression test on the motor here's the numbers #1 170 PSI #2 170 PSI #3 175 #4 170 PSI. All excellant compression numbers so no real uneven compression.

 I inspected the carb found a bolt was missing throm the base plate. I put another bolt and nut back on. I also pulled the distributor cap.
 I found that the cap points had some notches carved in them from the rotor like the cap had been crooked.

Possibily these 2 things maybe causing this.
I will change the cap this afternoon and take a test drive to see if the bolt mising from the base plate and the faulty distributor cap were the culprits.
