Engine Performance problem
2006 Mazda 5 4 cyl Two Wheel Drive Manual 120000 miles

My car started to run rough, took it to auto store and they hooked it up to scan for codes. They said misfire in #1. I have checked the plugs, the ignition coil and the fuel injector all good. What else could be the problem? This one is driving me crazy, help will be greatly appreciated.

P0301 Misfire at no.1 cyl-Check the compression for no.1 cylinder-you did the plug and injector on it and checked out-

Thanks for the advice, just did a compression test all were 75 psi exept for the #1 zero psi. Checked the coolant and it looks clean, oil looks clean too.
