MSD Opti Spark
MSD Opti Spark Is this a whole replacement for the opti??? I saw in Summitt that it was only $150, compared to the GM replacement that is $300.
Because if this is the case, I'll be getting the MSD.

NO it wont fix it because there is more to the opti-spark unit than the cap and rotor. But, if the cap and rotor are the problem and it is not setting any codes then yes it will fix it without having to buy the whole unit.

Verdad Gallardo That is usually the first sign of an opti. The resoultion of the crank/cam signal begins to breakup at high rpm causing the misfire. You might check your plugs if you have not changed them yet. Also check the fuel pressure and volume it could be going lean on the top end. Nine times out of ten though it is the opti. That is about the same way mine acted after I bought the car before it died.

whatever you do...... DO NOT buy it from autozone. just buy one from jason cromer.....fro like 230 or whatever it is....best deal around....he works at sam taylor..... www.samtaylor.com
DAMMMMM I got it all from summit 356 for jaccobs 150 for optispark cap 100 msd wires 55 for stock delco plugs. Almost finished with it. I'll finish it tomorrow night then strap on the *** dyno and see how how it runs.
top end breakups can also be the coil.
and yes im interested in how you liked the MSD stuff. at this point im still thinking OEM is just as good, but i dont know of anyone who has used the MSD stuff yet

I finished it Friday evening. It is a lot higher quality than the factory cap and rotor. It seems to idle a little smoother but it could also be in my head too. Since it seems new parts always run better. I went ahead and did a complete tuneup then put a jaccobs ignition system on it. Short term very happy, long term we'll see.

230 for the whole opti. i have put 3 on various cars. Helps out alot. Unless your running a stroked car and turning 6500 to 7000 rpm stock opti is fine. anything more than that switch to aftermarket delteq or something along those lines. if it was me i would go with orginal part. and for 230 dollars great quality. by the way the cap and button go out more than the optical sensor of the backplate does. Fyi. thats why more cap and buttons are sold than anything else. it cutting out in top end is a sure sign your opti is bad. id bet 100 dollars on it.

I pulled two codes from my car...
Ignition System Problem = High Res
Ignition System Problem = Low Res
does that sound like the optical sensor? the car will run fine until it warms up to temperature ~180 then it dies.
i'm planning on swapping to a vented opti while i do my cam swap but i'd like to know what it is, i have a good cap and rotor that i could put on it and sell...
