Hello:
This is my first post and is related to my recent acquired: a 91 Loyale sedan.
My question is: if the "Check engine" light dont turns on, is all in the engine OK?
Surfing the web I've found many pages with the method to perform a check and got the codes for my car.
I got this link and may be useful http://www.troublecodes.net/Subaru/
