Mazda 2002 Protege 2.0. #1 cylinder is not contributing with a P0301 code.

What is your question?

Ignition spark is strong, new plugs (and cylinder #1 is firing with plug laying on manifold to see it for myself). #1 Injector replaced, (old injector ohmed out fine). Noid light on injector harness lights and flashes as it should. Compression around 120 PSI and even across all cylinders. Vacuum reading is good and steady. Any ideas?

How long has your 2002 Mazda Protege had this problem?
