Anyone know what if anything goes here? I have a double ended bolt with washer threaded into the throttle cable bracket that is in-between injector 3 and 4. Does anyone have any idea of what goes into this bolt? Side note, I am getting a P0203/P0303 code right now so i'm trying to troubleshoot that and came across this. Makes me wonder if some ground wire connects to it or if its nothing at all and i'm wasting time. Help is greatly appreciated!
