I noticed last night that I think my 92 might be running a bit rich. While I was sitting at idle, i could smell a bit of a gas smell... any ideas? I've been starting to find that a bunch of the things I've noticed with my 2nd gen is common knowledge around here. Thanks!!!!

 

Mine runs rich as well. I replaced both O2 sensors at $115 each and it still runs rich. I remember reading somewhere that the fuel injectors will leak when they are worn, causing them to dribble fuel instead of spraying it, causing the rich mixture and making my check engine light illuminate and the truck run rough at idle. Anyone else have any ideas?
