My car popped a check engine light yesterday. The wierd thing is that when I go to jump the jumper and check the code, the check engine light completely goes away. I have a 96 Civic hatchback converted to OBD1 with a Ryewire harness, and Hondata S100 in a P72. I have been running the car for about 6 months and have had no problems.
I also notice that I have no vtec anymore.

Any suggestions would be greatly appreciated.

 

Bump, any ideas?
