I got new good wires ordered and gonna put back in that loom some how holding it away from alt. But hopeful it's the new cheapo wires cause this issue.. I'm ready to pull my hair out over this.

I recently went through a similar problem. Replaced everything but the opti (I was in denial). Finally got so bad couldn't stand it and decided to replace opti. But, when I pulled the opti out the dowel pin came with it. Apparently it had broken off and under high RPM's became unstable and caused the miss. Not saying it's your problem too but ya never know.

The reason I am saying wires is because it clears up. If it got bad and stayed bad I would feel the opti more likely.

Three hits it pulls great after wires and rerouted

good news

Do you have a under drive pulley-harmonic balancer? My SLP pulley was messed up and the computer was seeing knock about 5 k and would pull timing out causing a miss fire. Drove me nuts till I changed it back to stock and it ran perfect. Spent hundreds of dollars chasing this. Shoulda sent SLP a bill. Pure junk stuff

Underdrive dampers are a better mod on vehicles with more belt load, like those with belt driven waterpumps.

how was it showin a knock?

after driving a couple more times still has a very small sputter at 5k

The rubber damper piece was loose and the motor saw that as knock. It was on a LS1 motor..

What could cause the 5k miss.. it's small buy there?
It run 12.176@111.14mph last night. So it's not bad. . For cam only car.

Like I said a handful of guys have found a miss around peak torque because cylinder pressure is high and the spark has a hard time jumping the gap. Not all plug wires are all that good, not even new.

i did put new taylor wires and spacers on it tuesday.. that fixed the one problem at 6k an up. but not the lil miss around 5 k just slipt second..

Taylors are probably leaking at peak torque.

criticalx

Well alot ppl like taylors.. I'm not putting out that much power.. would a better coil help?

Not atall, what I am saying is the brand new Taylors are likely leaking spark, an aftermarket coil is unlikely to be any hotter and if it were that would only exaggerate the problem.
The stock 96 ignition system is rather good since it targeted 100K mile tuneups.

criticalx

so what kinda do i need? also i found it only does this when its warm.

criticalx

Coil wire was arching off radiator hose

how'd you determine that? did you just turn down the lights and stare at the car?

Could it be possible the valve springs are weak and the valves are floating?
