Ok so a few things Iím trying to figure out I swapped a 94 lt1 4l60e into my 78 el Camino motor seems to idle a bit to high around 1200-1300 at idle in drive and about 1500-1600 in park I have no vacuum leaks and tps tests correctly also have a few transmission issues but mostly tied to the vss not being connected to the speedometer but the idle issue not sure if itís a tuning issue
