yes no maybe so. i hope this helps. I'm having the same problem, I'm going to swap out the ignition coil and see if it helps

I'm with some others that have mentioned to look at the opti sprark. If you have tried different plugs, coils, and wires my bet is the opti. Pull the water pump, and balancer and take the opti out and look at it. I bet the inside is caked up and rotor is eaten up and the spark current is arcing to other paths.
I was fine till I started to add MSD stuff. Just the box might not do it. But the coil will eat up a stock rotor fast and it will jump inside where it eats up the paths in the cap and will disinagrate that rotor fast also. I had mine miss at around 4k.
I went to the MSD opti...the dayna spark is pretty problemtic from what I have read. MSD does have a cap and rotor replacement for 150......Which will be way better if you wanna try the cheaper route. I think and whole billet unit is still 500. I did the MSD billet unit it 7 years ago and with blaster 2 coil I have not had one issue since. But back to the stock unit......the cap isnt made of quility material enough for the high current of the aftermarket coils. I had stock coil on for 70k and changed coil and 5k later went to crap. Hope the info helps.

I would recommend Taylor 8mm wires in the stock location. Just make sure they are secure to the engine and do not have the opportunity to rub all over the inside of the engine bay or components w/in the engine bay that are not directly connected to the engine.

yea taylor is ok but ive heard issues as well.......espically with boots popping off the wire ends....plus their boots are too big and tend to hit alot of headers......
#46
They do fine for hooker LT's. The boots are far smaller than MSD's. I'm thinking the only reason why boots pop off is it can be a challenge to seat them onto the optispark. All I've ever ran are Taylors and have never had issues.
My question is where was the light show/where were the wires grounding out?
I had this same issue, saw that two of my wires were rubbing on the passenger side between the acc bracket and inner fender and were showing signs of spark. Just replaced plugs/wires and all is well.

Ok I've been having the same issue. I've replaced everything but the PCM and engine harness (plugs, wires, coil, ICM, sent in Dynaspark for testing, lifters, heads with new springs, cam, intake, rockers! Just put a new opti on from the dealer and I'm gonna see if that fixed anything. My Dynaspark was supposed to be good the last 2 times I sent it in, we'll see if the new opti does anything. The Dynaspark was the only constant through the different engine combo's. It will **** me off but for my sanity I sure hope all this time it was due to a mis-diagnosis on Dynasparks part.

Stock opti seems to have fixed my issue. It only missed in 3rd and 4th above 5K rpm so I haven't been able to make more than two "passes" on the street, but as of now it's finally gone. I have a race on the 23rd and I'll feel more comfortable confirming it's fixed after a day at the track where I can really push it.

Glad you fixed it!
I would've questioned the Autolites, the NGK's seem to be the overall favorite around here.
Good thing you didn't go with the Taylor wires-they suck. Many have posted arcing issues with them, even fresh outta the box. I had this problem also when I had the '94.
I had issues with two different Opti units, one was from a GM parts counter. The cure for my car was the MSD unit.
I also went with the LTCC LSx coil setup on the '94. BEST upgrade I did.
Wires. Much debated. Here's some real facts about wires:
Resistance per foot:
Granatelli 8mm Steel Solid Core Cable - 0.1 ohms
MSD 8.5mm Super Conductor - 71.6 ohms
Accel 8.8 300+ Ferro-Spiral Race Wire - 166.1 ohms
Jacobs Electronics EnergyCore 8.5mm - 178.3 ohms
Taylor Spiro Pro 8mm Silicone - 301 ohms
Mallory Pro Sidewinder 8mm Silicone Suppression Wire - 313 ohms
Moroso Blue Maz Spiral Core 8mm - 661 ohms
GM stock LS1 - 702 ohms
GM stock LS7 red - 1554 ohms
Magnecor KV85 Competition 2.5mm - 2053 ohms
My '99 ran the best with the Granatelli wires.

The Granatelli wires have a great warranty and are super tough. I'm very happy with their construction. I have no issues with EMF with them.
