Answer 1

Year, make, and model please. First off how old is your vehicle? Second, is your fuel cap on and not broken? May have a leaking gas tank or hose. To little information to go on.

Answer 2

You ave bad 02 sensors which are causing your truck to dump to much fuel in the motor causing the misfire which is confusing th cat sensor. Change your 02 sensors and this should fix the whole problem. Also tighten your gas cap. If its locking gas cap replace with non locking. Lock caps are prone to eaking. Let me know how it works out.

Answer 3
