Misfire po300 on 2.2L

This and po172 showed up while I was 600 miles from home at a funeral. The car was missing badly.The plugs on cylinders 2 &3 were extremely worn and smelled of gas. I replaced the plugs and the ICM after reading a GM update. The car ran fine all the way home. Now when it is cold-misses bad, po300 shows up. When car reaches operating temp, runs fine. I am going to replace O2 sensors, cause it's time & I figure they are fouled at this point. Any ideas on the problem going away at operating temperature?

Are you sure that the plug gap is correct? and did you use the recommended plug when you changed them? You might also try running a can of sea foam thru with a tank of fuel to make sure your injectors are not dirty. Also check your fuel pressure.

SOURCE: Ford Crown Vic p0300 random cylinder misfire

take a look at the EGR valve it could be either vacum controlled or electronic either way what seems to be the problem is that the valve is stuck in the open position until the engine warms up you can gently tap the egr valve with a small hammer or a screw driver and you can see that it runs smooth, now if the egr valve is vacum controlled replace the valve. if it is electronoc controlled replace the valve and the module for the egr valve.

SOURCE: Hard start when cold, running rich, poor fuel economy

Chrysler has a bulletin out for a simular condititon that involves replacing the pcm. Heres the bulletin number 18-005-04. This is only 1 possible cause , Fuel pressure, coolant temp sensor, thottle position sensor all can cause like problems. Seeing sensor values and fuel adaptives with a scan tool helps pin point problems.

im a tech in the bronx and i dealt with the same code for the misfire. burt i realized that there wasnt any power to the coil of #2 cylinder. I replaced the sensor mounted on top of the air filter box, which solved this problem.

SOURCE: will a bad knock sensor cause a misfire. car is

A Bad Knock Sensor will not cause a misfire, unless the advance is off due to a faulty Knock Sensor. The O2 Sensor will cause a random misfire.

Good luck on this repair.

I would say its the coil. A crank or cam sensor could cause one cylinder to miss, or go completely dead, but I doubt it would affect two cylinders. And you would get a code for either sensor.

My mercury sable 2002 motor Ustyle idals bad code p0316,301,303 come up changed spark plugs and wires still showing same codes what should i check now


PO301 & PO 303 are cylinder misfire in the cyclinders
indicated by the codes last number #1 & #3

Spark Plugs get replaced every 3 years or so & have
nothing to do with resolving any misfire issues, unless
they were in the motor for 80,000 miles & worn out

Spark Plug wire easily last 12 to 15 years or more &
usually only fail because they are mishanded & too often

You problem IF the codes are correct & they are not all the
time,is a bad ignition module or individual coil if that is
what you have

2002 escape 3.0 idle fluctuates and misfires when driving


No such thing as a tune-up

All you did was replace spark plugs which should be
done every 3 years

Oxygen Sensors get replaced at 100,000 miles which you
also did

You most likely have an intake gasket leak,smoke test
the entire Evap System & Engine

You also are have bad igniton coils

I have a constant miss in my engine. I've changed the wiring, cap & rotor, plugs and fuel filter. What could be the problem?


Have you performed a compression check? You could have a sticking or Mal-adjusted valve, bad cylinder or other problem -- the test would reveal your answers more precisely...

Cylinder 3 misfire


Misfire codes (including P0301, P0302, P0303, P0304, P0305, P0306, P0307 & P0308) indicate that there is a misfire in a cylinder, the last number indicates which cylinder has the problem. If something is causing a miss in random cylinders or is affecting all of them, a P0300 misfire code will be stored in the car's computer. It's always smart to begin with the basics. Also consider the mileage and service history when diagnosing a misfire. Higher mile vehicles are more inclined to have mechanical issues with the engines, like low compression from worn valves or rings etc. Any accompanying codes should also be considered in case they may be related. If the spark plugs are worn (excessive gap) or the car is past due for a tune up, it may be smart to go ahead and start with spark plugs and spark plug wires and go from there.
The most common misfire causes on the cars I've worked on have been:
  1. Spark plugs
  2. Spark plug wires
  3. Ignition coil
  4. Fuel injector
  5. Wiring to fuel injector
  6. Timing Belt (if eqipped)
  7. Vacuum leak or stuck open EGR
  8. Contaminated fuel or bad fuel pump
  9. Weak compression
  10. Blown head gasket

YOU COULD HAVE A CLOGGED OR FAULTY FUEL INJECTOR. OR YOU COULD HAVE LOW COMPRESSION ON THAT CYLINDER.YOU COULD HAVE BAD WORN OUT VALVES IN THAT CYLINDER.
