What does code P0301 mean on a 2001 dodge ram?
Trouble code P0301 means:Cylinder 1 misfire detected
Causes A code P0301 may mean that one or more of the following has happened: Faulty spark plug or wire Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector Burned exhaust valve Faulty catalytic converter(s) Running out of fuel Poor compression Defective computer You really need to go to a good shop and have someone diagnose this for you!
p0300 is a general misfire code, and p0301 is a misfire on cylinder # 1. Most of the time a tune up will usually fix the issue. While you are checking things it wouldn't hurt to do a compression test while you have the spark plug out. If you have done a recent tune up recheck the plug, and possibly check the fuel injector.
