I drive an 88 suburban. it has a 350 in it. If you look in my sig you will see what the burb has in the engine. The problem is at idle, it will foul the plugs. It is TBI with A dontov 30 30 grind cam and L98 heads. Its scary powerful when it runs but the ECM (I don't think) can handle it. What do i need to do to get this thing to idle without fouling the plugs? Thanks in advance!
