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.

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.
