Default Opi spark

Finally put my '94 coupe on the road. Just 200 miles so far. It burped just once on acceleration for maybe a second then took the gas. I drove home 25 miles after with no trouble. Question; will the Opi spark be intermittent or does it go out all at once? Also, I've seen after market ones advertised fro way less than the GM Opi and some claim to be better. Any advice would be appreciated.

It CAN be intermittent.

It's a crap shoot, which one you buy. 3 people may say they have had good luck so far w/brand xxx but no luck w/brand yyy....3 other people may say the opposite. I have a NAPA unit in mine; has worked great for just over 4 years now. Do I think the NAPA opti is "it"? No I don't...but it hasn't been a roach, either, so...IDK.

My 94 would stumble and fart under the hood with no codes. Then got worse. I changed the front two o2s never ran better.
