Thanks for replying. EGR is gone. Compression is good motor is new. Trying to pull a vacum on the advance does nothing you just pump.away and nothing happens. I willpull the plugs and see what they look like. This started as kind of a spitting and sputtering and as the rpm built up the engine would clear up and run fine. It just recently started what it's doing now. It really doesnt spit and sputter it just feels like the motor is bogging all the time now. The engine doesnt run crisp and clean. Kind of sounds like is going BLAHHHHHH, BLAHHHHHHH. I know that's weird but that's what it actually sounds like doesnt want to really build any rpm. It will hardly get down the road. It used to run as fast as you had balls to drive it. 90 to 95 was easy I just didn't want to push my luck.
