Check fuel injectors, fuel pressure regulator, air filter. cat converter, O2 sensor. failure of any of these wastes fuel. air/fuel ratio should be normal.

Car is sluggish, Low Acceleration, Check engine light flashes, Code reader indicates #1cylinder is out


Of course your car is sluggish, cylinder number one is misfiring, that is why the flashing check engine light, if you continue to drive this car this way you risk the exhayst system overheating and starting a fire. Ge the car tested for the cause of the misfire asap.

Engine light comes on - Code shows P0300 and then


OBD II 300 Random/Multiple Cylinder Misfire Detected

When the misfire monitor detects a misfire, it will trigger the check engine light with the specific cylinder number as the last digit in the P030X code. For instance cylinder 1 misfire is P0301, cylinder 2 is P0302 etc. In this case we have either multiple cylinders misfiring, or the computer simply can't determine the specific cylinder, and as such we are left with the P0300 in computer memory.

Possible Causes:

Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect Fuel Pressure
EGR system concerns: leaking EGR valve or restricted ports
Base engine concerns: low compression, valve train problems and timing issues
Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues

OBD 2 code showing 301


P0300, P0301, and P0302 are all misfire codes (cylinders #1 and #2, and a multiple/random misfire). The only time I've heard of this being related to a crank sensor is if the sensor were loose. Furthermore, a crank sensor issue should affect all cylinders equally. So I'd expect you'd have the P0300 only, or all the codes you have plus P0303 and P0304 (and P0305 and P0306 if a V6).

You should continue checking your secondary ignition system. Presuming the wires and plugs made no difference in the codes or condition, check the coil. You'll want to do your checking when the problem is occurring. Perhaps even mist the wires and coil with water to see if you can see a spark jumping. If you do indeed see a spark jumping, that is the location of your problem.

Another strategy you can use is to take the #1 and #2 plug wires (if accessible) off the plugs and just set them back in place without clipping back onto the plugs. Then, start the car, and gradually pull the wire(s) off the plug(s). The spark should come out of the end of the wire onto the plug. If it comes out of the coil or the side of the wire, then the problem is in the location of the spark.

If you're unable to find a secondary ignition problem, then you should begin investigating whether you have a fuel delivery or internal engine problem causing the misfire. Most engine issues will show up with a compression test. If you indeed are only misfiring on cylinders 1 and 2, you can swap those injectors with the others to see if the misfire follows the injectors.
