Sounds normal for the most part. If no check engine light (CEL), then its probably just injectors. One thing to be concerned about if there is a chattering coming from the engine is the tumble flaps in the intake manifold (you will get a CEL with this problem). Myself, along with a couple other 100k foci duratecs are having or have had this problem.
Just got done doing a sea foam treatment. Already quieter. I'll post the video as soon as it's edited.
Also I live in a town with a general store and a couple gas stations. The likeliness of me finding a mechanics stethoscope is slim to none. Thanks though.
