hey guys my bother's 95 4runner is missing again and his wife drove it up here (Ft Worth) from Midland and it started to not fire in one or a couple cylinders. she flew home and her mom is going to drive it over to my house so i can look at it and fix it. it's been missing before but we fixed it and now it's doing it again. so i'm going to look at all the spark plug wires and distributor and spark plugs. anything else i should look for? the thing that made it miss before was a vacum leak so i'm going to look for that as well. any help would be much appreciated.
