hey can anyone please please please post me a picture or diagram of where all the vacuum lines are supposed to go on a 91 mustang...after tryin to fix my timing i moved my distributor over about a half turn and now it starts up, but it sounds like a lawnmower and accelerates like a school bus, backfires some too, its so wierd..maybe my vac hoses are misrouted or something i dont know, i also found that where the pcv valve was supposed to plug into my upper intake a screw was plugged into a piece of hose, so i replaced the pvc valve and hose...im at a complete loss here, can anyone help?
