Default Code throw

I have a pretty highly modded 85 corvette. This problem was present before my recent cam and intake swap so I know those are culprits.

The car will drive fine then throw a code and have the dash light. It will sputter and run ****ty so i throw it in nuetral and restart the car. This clears the code and its fine again. It comes and goes. Might not happen for a month or 3 times on one drive.

Any ideas?

The code is stored until the ECM looses power. All it takes is a paper clip and the ability to count the flashing SES light.

its not so much doing it as it never does it while im just driving around. as soon as i restart my car the car runs perfect.

will a scan tool still pick it up if the dash isnt telling me to check engine?

Yes, and so will the paper clip method, as long as the battery has not been disconnected.
