So I have ran the Bronco through emissions twice in the past couple of weeks failing each time. At first I thought it was the timing (was off 4 degrees). Nope, not that. Check for codes, no codes. All the emissions equip. is there and functional. The previous owner says the Cats are not that old. It only fails one of the four tests. HC (PPM). Idle limit: 220 Bronco: 643. What would cause this if no codes are being thrown. The motor has 59k miles on it. It's never had an emissions test before this, so the previous owner has no idea and neither do I.
Here is the test if you can read it...
