The question is that CEL #90 came on...is there anything more than me just not tightening down the lovely gas caps 3 clicks? I haven't been running a stock ECU for the last 13,000 miles, and I just reinstalled it until I have a Hondata chip burned for the new non-TODA cammed car.

Technical description of CEL #90:
"Evaporative Emission Control System leak detected in the fuel tank area"

Thanks,
Austin
