Query: Better than nothing

As the old saying goes "Jack of all trades - Master of none". This manual tries to cover five different GM models and as a result does none of them well. While attempting to diagnose a fuel feed problem in my 1994 Grand Am I found several errors in the documentation. The manual will cover one type of system in a particular year group and gives you the infamous... other models similar. So, while it's better than stumbling around in the dark I can't recommend spending $22 for it.
