Yed.sort of. I gues Im just wondering where the interuption is coming from?

I have seen others have trouble with hall effect sensors,something to do with a ghost signal? Or could they pick up on arcing inside the cap and interpret that as a signal? Thats why I suggested the cap,as I've seen plently of arcing with a juiced ign and a non ribbed cap.

I hear you and thanks for helping me brain storm!

We can rule out the cap because of the set up we did with the LS Coils that came off a running car which have the COP Coil on Plug "its own spark plug wire straight to the spark plug" With this set up the cap is not used nor the standard spark plug wires. However the HALL sensors for the Crank and Cam signals are used to tell the coils when to fire and the Injectors are supposed to squirt fuel. So my thinking is it has to be something interrupting the Signal like you are saying that is causing the sporadic miss fires which are on every cylinder that was verified with the strobe. This strobe test can rule out a fuel problem so I am thinking that it is the Crank Sensor inside the Distributor.

I did notice that when I bought the distributor, "used", it did have fatigue on 1 of the pick up wires at the sensor, it looked like it got over heated and had signs of burning. The tuner when he was setting up the 50* angle noticed it also, I asked him if he did and he said YES. We got so involved in chasing the problem that we forgot to pop the cap and take a peek at it again. I would just about bet that if that wire was fatigued that it is now starting to fail messing up the signal..............

When the engine was first fired i did not hear a miss at all and as we went along it started off lightly which you can hear at the end of the second video and in the third video it was progressively worse for dang sure.

I am thinking it most likely is that fatigued wire that I seen when I first got the distributor....... Dang it
