P0301 Cylinder 1 Misfire Detected - Diagnosis and Solutions for 2000 Ford Taurus
I recently replaced the spark plugs and ignition wires on my 2000 Ford Taurus, but the P0301 cylinder 1 misfire code persists. The engine does not show any rough idle or dead miss, but I'm experiencing slow acceleration under load. My vehicle's inspection is due at the end of this month, and I'm seeking reliable troubleshooting steps to resolve this issue. Any insights on possible causes related to ignition or compression in cylinder 1?
Have you verified spark presence at cylinder 1? A lack of spark could indicate a faulty ignition coil, even after replacing the high-tension (HT) leads. Additionally, check for insufficient compression in cylinder 1, as this is another common cause of P0301 misfires in 2000 Ford Taurus models.
