Best Answer

Your distrbuter or bad plug wires The V10 does not have a distrbuter or plug wires. It does have what we call COP or coil over plug. The V10 has a history of the #9 coil issues. Check with your tech to trouble shoot coils. Sometimes, it's not the coil but the coil harness.

What can cause cylinders 2 and 4 to misfire on a 2001 ranger?

Misfire can be caused by any condition that doesn't allow for full combustion in an engine. You don't specify what engine you have in your Ranger, but look for things common to both cylinders. Are they on the same ignition coil? Are they next to each other on the engine? Causes can be almost anything, from a bad spark plug to a mechanical fault in the engine itself. I cover this information in my upcoming book Automotive Driveablity: A Guide to Engine Performance Diagnosis. Feel free to visit me at www.autoservicetech.com. I also recently wrote an article on misfire diagnosis for MotorAge magazine that will be listed on my home site soon.
