Running to rich 88 Sentra
New to this so bare with me. I race a 88 Sentra/coupe in what we call Bump-n-Run in Montana (It,s a combination offroad racing & demo derby). My problem is at idle and at rpm's lower than 4000 it runs great, over that it starts tearin up and turns new spark plugs black in just a few minutes. I've changed plugs,wires,cap,rotor,all filters,vaccuum lines,coil, and doesn't change. I would like to be able to run codes on it but the car is totally stripped out so I don't have any flashing lights to count. I hope someone can help me out racing season is about here.
