Any idea why my ecu keeps randomly throwing a code 68 every once and a while? When it happens the car hiccups for a second and then the code comes on. When i turn the car off the code dissapears. Whats strange is that 68 isn't even a real code. I checked it and its not listed. When tuning a prelude today my ecu even threw the code once while it was running his car. Think a connection is going bad? Thanx for your help.
