Mechanical tips
 

I'll be the first to admit I don't know everything about cars and how to diagnose issues with them. This forum is really a great place with some very knowledgeable people willing to help. I get a lot of good information from YouTube channels as well. I began watching tips from a user channel briansmobile1. He is a good mechanic and offers some great information. richpin06a is another user's channel. This guy works on a lot of Saturn's as well as others. EricTheCarGuy offers good information too.
Now if you want to watch someone that knows his way around a scan tool, I recommend the user channel ScannerDanner. I especially like his video of the Mini Cooper no start. A car bought at auction with what appears to be a seizng engine.
If you can recommend another user's channel please let me know.

LOL damn i was going to say every one you already said. another one is realfixesrealfast.

A scan tool is like a book: You have to know how to read and understand what you're reading. Scannerdanner is an instructor, and a darn good one.
