FORD FOCUS COMPRESSION PROBLEM

2001 Ford Focus • 14,000 miles

I have a problem with my car cutting out or missing while driving it. It has not quit on me. It hasnt caused a engine light to come on yet.I have changed the plug wires and plugs a few months ago, before this ever started. This has only been going on for 3 weeks. Had the fuel filter changed a week ago. Made no difference. Tried a gas treatment, still no change. What is causing this problem?

Start with compression test.

Is there spark to all plugs?

Injectors should be cleaned professionally as additives have little or no effect.
