SOURCE: 2005 chevy colorado runs rough and gets bad gas mileage.

Sounds like it needs spark plugs and wires, and a fuel system treatment.

it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps

Cylinder order on 2011 dodge dakota 3.7


neither if if ran fine for a few days after your repairs
misfires are more likely from problem injectors, low fuel pressures or injector wiring problems
use a couple of vans of quality injector cleaner first

P0300 random misfire detected


Check spark plugs and wire set. I had a mechanic replace my spark plugs by hand and he didn't tighten one well enough, when a different mechanic figured out that, he had damaged the wire set. A pin hole in the wire set caused it to shake uncontrollably, especially at higher speeds. I would check that first, it's much less expensive than replacing the coil.

Replaced 2 coil packs and still running rough 2003 trailblazer


try replacing or cleaning the injectors
when misfiring moves around it is seldom the coils , plugs and any thing else connected to spark but dirty fuel, low fuel pressure and dirty injectors or injector control
use a quality injector cleaner for a few tankfills

2004 Jetta 1.8T started idling rough at low rpm, OBD says random misfire....


spark plugs? either current ones are bad, or maybe you replaced recently with incorrect ones (most autoparts stores don't have the right plugs for 1.8T...need to go to dealer or ecstuning.com)
-or-
coil packs?
the OBD scan should tell you what cylinder is misfiring. try swapping the coil packs around and see if the misfire moves. if it does, then replace the bad coil pack (might just want to do all 4). if not, trying swapping the plugs around...same idea.

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.

I have a 1997 ford explorer awd 5.0 and it had a misfire in #3


Could be a bad valve, carbon, etc... i.e. something inside the motor.

First thing to do is double check your parts. Swap the coils from one side to the other. Reset the light an drive. if it comes back as a Cyl 3 again then its probable a inside the engine if everything else outside has been replaced.

Misfire


Well, the P in the code means powertrain.  As far as the code specifics, 
P1313 Misfire Rate Catalyst Damage Fault - Bank 1
P1316 Misfire Rate Exceeds Emissions

I would say check your spark plugs and wires.
