"Cat not Ready" smog test failure
My '04 GT3 failed its smog test today - another "Cat not ready" failure. Prior to taking the car in for the test, I swapped out the FabSpeed cold intake with the stock unit but it still has CarGraphic mufflers that didn't appear to be an issue with the smog tech.
Back in Sept 2016, I replaced the battery at 56,132mi. It now has an additional 600+miles (56,800mi) most quick freeway runs at an average speed of 70-75mph.
Per the smog techs suggestion, I drove the car about 30 miles with the cruise set at 60mph. But the "Cat no Ready" condition persists.
So... what the latest wisdom on getting this resolved? Has having the car idle for 20 miles work or is there another procedure that works. Thanks
