2000 Ford Taurus P0306 Cylinder Misfire Diagnosis and Solutions

Model: 2000 ford taurus Fault Code: P0306 Posted: 2008-07-10 04:43

I have replaced all spark plugs, ignition wires, coil pack, and swapped out the fuel injector. A compression test showed consistent readings of 120 psi when the adjacent cylinder was removed, lasting over five minutes. The engine warms up roughly and exhibits sporadic misfires. No visible vacuum hose leaks were detected, though I cannot rule out a missed leak. Any insights or troubleshooting steps for this P0306 fault on a 2000 Ford Taurus?
