After a lean burn conversion do these solenoids do anything? Can they be removed? I'm trying to clean up my engine bay so planing to remove the computer wiring and such. I also need to clean up the wiring for the conversion, it was kinda just hacked in here and can't seem to find a good wiring diagram that shows what can be eliminated and what I still need, but that might be another post I'm trying to get stuff done while I got some time that doesn't cost anything and will give me room and make it look cleaner under hood. 86 5th Ave if it makes a difference. Thanks.
