2000 Cadillac Escalade V8 Four Wheel Drive Automatic 87000 miles

I have a code of PO301 (missfire cyl. 1) I have changed the plugs, wires, cap & rotor, PCV valve & it stills runs a little rough & I still get the code after I clear it. What else can I do to make it run right?

Do you
have the same problem?

Most common for a misfire is spark plug and the ignition system
but that s not the only cause
check fuel injector and compression
vacuum leaks too
on GM injectors may be at fault
