I spend hours today swapping my stock mid-pipe into my car because it was smog time. after I was done with the swap, i disconnected the battery for 5 minutes, to turn of the mil. after reconnecting it, the mil was off. I drove it around for about 10 min, and then took it to the smog station. after waiting forever, the guy comes in and said it failed. he said the the obd2 read a mil even tho the one on the dash wasn't on. he then told me I had to drive the car for a week after clearing the codes, so the cars computer can run its self tests. other then that, the car passed all other tests with flying colors, due to the 6cats ford so graciously put on the car. anyways my question is do I really have to drive the car for a week before I can bring it back, or is there another way around this.
