I purchased this manual to do a head gasket replacement on my 1999 Wrangler. Haynes was always the resource for serious mechanics many years ago but that has obviously changed. Trying to pack to many vehicles in to one manual is a bad idea for starters. My biggest complaint is that once I had my engine back together I put on a new distributor, rotor, wires and plugs. According to the manual the #1 plug is located in the back. That seemed odd to me but since I took the wires off two weeks before and didn't pay attention to the firing order since I had a manual. After wasting several hours of my time I went to the Internet for answers. The first thing I found was several references to #1 being in the front right were I expected it should have been. After 2 minutes to switch the wires around the Jeep fired right up and sounds good. How can you publish a manual with a major error like that?
