I went to have my Emissions Test today and was told that the On-Board Diagnostics system is not ready to make a determination regarding the pollution control systems on the vehicle.

I'm running a 93/tune from Brenspeed that I've had for nearly three years, never had an issue with it passing in the past. Several months ago, l had my alternator replaced. I can't recall if I re-tuned it after the work was completed. I'm almost positive I did. I re-tuned it again after the testing, hopefully this will work.

Any additional suggestions? Thanks!
