2nd gen 3sgte swap , 94 gt , hour from home at girlfriends , car ran fine all the way here , then died taking a corner when i shifted gears , then started up and made it to her house then died when i let out throttle , now starts but wont stay smooth unless above 2000 rpm , any ideas , stumbles and dies below 2000 rpm , no codes

vacuum lines messed up? did you try unplugging the AFM?

havent tried unplugging it but did check with carb cleaner for leaks and checks lines with no luck

try resetting the ECU by unplugging the battery for 10-20 minutes

Sounds like a bad maf sensor to me bud

idle air control valve

i am leaning towards maf myself as i was able to baby it home and a fewtimesup a hill fit would buck if there was any actually load
