Question about 2004 Dodge Ram 1500
2004 Dodge Ram 1500 4.7
Check engine light came on. Engine running fine. Took it to the parts store and got the code checked (MIsfire #1). Replaced spark plugs in all 8 cylinders with Champion Dbl Platinum. Engine started running ruff with a small miss when at idle. Checked code again came back with Misfire #1 & Multi Misfire. Disconnected battery reset computer. Light went off but still ran ruff. Light came back on after 2 days. Check code again Misfire #6. Help.......Coils?????
A multi misfire may mean that one or more of the following has happened:
Faulty spark plug or wires, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector(s), Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.
The engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wire, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the the problems were faulty fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.
Good luck and hope this information helps, keep me posted, be glad to help you get the truck running 100% again. Not sure if your running a K&N air filter, and if you are there may be a flim of oil on the MAF sensor that is making you run lean. You may want to spray down the MAF sensor with a can of MAF cleaner.
