Definitely going to look into that, but I'm wondering why it would take 7 months to cause a problem? I've put about 15k on the truck since I changed the distributor last January.

Dirt and grease in the connectors of the cam sensor will cause misfire issues. Clean them and apply di-electric grease.

Change coil, I had an msd and after about 3 months it would die at intermittent times, drove me up a wall because it always tested good
finally i just changed it and no issues since, as a matter of fact it is still sitting on the floorboard

VWandDodge, In this process, the crank sensor has been replace twice, and the cam sensor has been replaced three times. The last round on both, they were done at the same time with OEM parts, and the connections were clean, and I used di-electric grease.

For the guys talking about fuel sync. Is that the same as the "relearn function" That can be done with a Solus? Or is that a different deal? After the distrib swap, which was the first time I changed the cam sensor, my cousin hooked it up to his Solus and did a "relearn" on the computer 2 Months after. It has not been done again though, after the cam sensor was replaced the second and third time. The cutting out / or the bucking it's doing going down the interstate didn't start UNTILL the second time I replaced the cam sensor (under parts warranty from Advanced). The third time I replaced it was an OEM part, as well as the crank sensor done at the same time.

Also, in an effort to try to figure it out, and running out of things to replace. I put a second new set of plugs in this weekend. After researching this forum, I decided to go with Autolights, one heat range cooler then stock. It made the bucking problem worse. UGG.

I don't know if a Solus can do fuel sync. But as far as I know it's not a relearn thing. It's a "reset the fuel sync thing". Maybe someone who has a Solus will chime in.

Thus, a misfire is detected because all of that unburnt fuel shows up at the upstream oxygen sensor.
How does that show a misfire on a certain cylinder? The misfires were on 4 and 8.

Solus will be able to set fuel synch. It does everything the MT 2500 does and then some....for a lot more money...

As the engine goes round and round you get four exhaust gas pulses per revolution which appear as electrical pulses on the output of the upstream oxygen sensor. If you happen to know the crank and cam positions and engine RPM along with the approximate exhaust gas velocity you can then extrapolate which cylinder each pulse came from by its position in time. If a pulse goes missing or its amplitude is too low, there's a cylinder not firing or not firing well.

IT WORKED! I took my truck to the local Dodge dealer yesterday. They said I had the dissy 11 degrees off. Runs great now. Thanks for all the help. I wish I would of known that in the first place.
