I believe it is the injectors... I have the same problem on my 1993 which is PROM computer and speed density... I know it is different, but my guy who tuned it said my idle is high because my IAC motor is stuck halfway, so it idles at 2k and it is running rich because the fuel injectors are messed up... when i drive it, my eyes burn due to the richness, and i drove like 15 miles and it went from full to 3/4 of a tank of gas...
i felt the exhaust on my passenger side and it was really warm coming out the tip, and the driver side was cold... like i was holding my hand in front of a fan... sure its not true dual exhaust but it should still be warm... yet cooler than the other side... so i ordered new injectors and a new IAC, and that should work... i get them tomorrow, so i will let you know... OH my motor is rebuilt, with a cam, and i had my fuel rails with the injectors still on them sitting for 9 months in my garage... so they could be gummed up...
