My 1995 does this too, I can't figure it out. I plan to fix it with MSpnp though.

The issue is not resolved yet. I still get the CEL after a few miles of driving. The car doesnt behave any differently when it happens.

Right now Im having problems with my DIY MSPNP not working. It think its not reading RPM's. My sensors are reading, but I'm not getting any spark or fuel. I will work on it further this week.
