I have heard time and time again that I should do a compression test to make sure my engine is healthy before spending $$$$ on FI. Problem is, I really don't have a clue what I am doing under the hood beyond oil and filter changes. Is this something I should try to do myself, or do I need to take it somewhere?
Thanks!
Even when I have the right tools, I don't always know what to do with them.
(Except Duct Tape and WD-40... I have those 2 down!)
