Fuel smoking problem in 94 5.7 chevy

\015 I just put an engine out of a 94 2 wheel drive chevy 1500 in a 94 4 wheel drive. it smokes like its running rich but the computer says its lean on idle. just replaced esc module didnt help much. but when i unhook the knock sensor it clears up a lot but not completely. what else can i do? i should say at an idle its fine it only smokes when i hit the gas now.\015 Posted / edited by AnonymousUser on : 11-11-2019
