Enough misfires can cause other problems. How many miles on the tune up ( spark plugs, wires, air and fuel filters ) ?

SOURCE: Check engine light

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.

You could have a bad coil pack or a bad fuel injector. swap out the coil packs from the misfiring cylinders and put them in the cylinders that are known to be firing correctly to narrow it down to determine if it is the coil pack first. When is the last time you changed the spark plugs? Pull them out of the misfiring cylinders to check the condition of the plugs.

Po300 code multi cyl misfire any sugg


The code you got may not have indicated the correct coil, that was bad

I would put the old coil back in #6 & either walk the new coil to another cylinder, or get professonal help in the form of a scan tool in Mode $06,
if applicable on your vehicle & check for misfires that why

Forget the PO300

1996 tahoe , codes are showing random misfire


Do an injector balance test and a cylinder leakage test. Lets make sure its not fuel related. Most important lets make sure you don't have a vacuum leak.

2006 dodge caravan, 6 cyl. relaced cole, sparkepugs and wires in oct. 2009. Engine is reading #2 cyl. misfire again. Why


Firts time swap spark plug & ignition coil between two different cylinders and read again if the same #2 cyl. misfires !
If #2 cyl. is OK and another cyl. misfires then spark plug or ignition coil is out of order and must be replaced.
If #2 cyl. misfires again then #2 injector must be checked !
If ignition coils & spark plugs (complete set for 6 cyl.) are replaced then you must check #2 injector !
