Whenever I am coasting in neutral or just sitting at a light, my E30's CEL comes on. It goes away as soon as I give it gas, but anyone know why this is happening?

vac leak? Do you have oscillating idle?
Otherwise, maybe tps? I have no idea when it comes to m20 management, so I'm picking at straws, but your initial description leads me to ask these questions.'84 318i M10B18 147- Safari Beige
