Jeep Information



Engine:AMC 304


Failed emissions by a hair.
Living in AZ now, so I'm new to having annual emisions tests. I just bought a 1979 CJ5 with an AMC 304. It passed emisions last year and no engine work has been done. I went to get it tested the other day and it failed. Carbon monoxide is reading just a little too high. What can I do to get her to pass the test??

Yeah, hi, it's me again.
Just looking for some wisdom from someone who knows these dirty AMCs. Anything will help pertaining to my emisions quandary. She's running too rich. I feel like I'm going to pass out idling at stoplights lol.
