Got pulled over in Ft.Collins for not having a front license plate and driving a truck in pieces. He wanted to make sure I didn't steal it.
Idle back to 650 after resetting the computer
First test no CEL - second trip through (4th pass) P401 came on. They did change the law so a CEL isn't an automatic failure. I had to run the test 4 times because the first passed the sniffer but, they failed me for not having two catalytic converters. The gal there was really nice and she crawled under the truck and verified the two bumps were in fact two cats.
