python Posted August 12, 2007 Share Posted August 12, 2007 What's the firing order for 91 LS.......... look at ur distributor caps, the wires from each plug is labeled on them, if its in a circle then u use the ones in a circle depending if u have it on the left or right bank, the number one piston is labled on the head where each plug is, if u have any doubts as to which is number one then stand on the side of ur car and the head that is furthest forward is number one, if u dont understand any of this then dont work on ur car, have a mechanic do it, also ur plug wires should be labeled as well , DO NOT USE AFTERMARKET PARTS ON THIS CAR!!!!
