2002 Mercury Cougar Q&A
2002 Mercury Cougar Question: Won't pass DEQ Emmisions but no engine lights on?
There must be a reason for not passing the test, like the drive cycle is not completed, or something similar. We need to know the exact reason to be able to help you. Zee - ZeeTech
no recall I see. what recall are you referring too?? you may have monitors not set for some reason like you replaced a battery. Roy - mastertech6371
