ok heres the story, i have a 91 turbo, when i first got it the egine was beyond repair rod threw the block, lmao . so i picked up a rebuilt stock n/a engine with a metal head gasket. i am running the n/a engine now on turbo electronics. the engine runs fine once i get it to idel correctly, but every time i start her up it wont stay running, it will stay at like 800-900 rpm then die out. one i give it a little gas it corrects itself and then will run fine, it sounds like the afm is allowing to much air in, i thought that because i have n/a injectors that might be a problem, just lookin for others opinions thanks.
