I am having a problem with my 97 Camaro z28. Mostly stock. Mods = SLP cold air, short headers and Hypertech programming. I broke my timing chain about a week ago. I am doing all the work my self. In the past have replaced my opti-spark twice and plugs, wires and water pump once. it has 202,000 miles on it and has no blowby yet.

Work done since I broke the timing chain. New chain and gears, exchanged opti for new one at Autozone(lifetime warranty). I used the old cap and rotor cleaned the very well with Superclean and cleaned all the contacts with emery cloth. I lined the dots up on the timing chain and gears crank at 12 oclock and cam at 6 oclock. Installed every thing fine but the car misses like hell. and my code reder says p0300 RANDOM MULTI cylinder miss fire.

Could I have damaged the cap or roter by getting them wet during cleaning or maybe the optisoark is a bad one out of the box. Possibly I was off a tooth on the timing chain(not likly but possible). Any help would be appricated.

Mean Green Z28

Any resolution to the problem yet?

I know things can get pricey, but for all that work to get to the opti, I would never put used parts back in. I would have installed a new unit and then you can have peice of mind that it should work. P0300 is hard to diagnose, try the usual, check plug wires, coil wire, opti harness, etc for damage burns or corrosion. Good luck with it.

Good point.




I know it's more expensive, and I'm not saying this is your problem, but for $150 it's not a bad investment to know you won't have to deal with this issue for a good long while.
