1994 z28 supercharger

Hi I have a 94 z28 and I have a feeling the opti spark is a bad. The idle will go up and down but the rpm stays the same. It will also backfire every once in awhile. Does anyone know what some symptoms would be that would let me know for sure? Also what it might look like if I need to buy a new one? Any suggestions will help a lot thanks!

Re: 1994 z28 supercharger

Hi, you have posted this in the LS1 tech section, and titled it supercharger? You may not get any good answers over here, but first off, have you scanned for codes?

Oh my bad. I have not checked for any codes because the check engine light does not come on. I think that it's just got a bad plug in the opti or because it got wet.
