A P0301 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #1.

Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present

Causes: A code P0301 may mean that one or more of the following has happened:
* Faulty spark plug or wire
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector
* Burned exhaust valve
* Faulty catalytic converter(s)
* Running out of fuel
* Poor compression
* Defective computer

Possible Solutions:
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
* If there are symptoms such as 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 wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Test it and send us news.

Drivimg down road excellerated and car bogged down and died could this be a timing chain replaced electronic modulator and now gets fire but still wont start


I doubt it. If the chain failed, the cam would not turn and you would not get spark.
If you have normal compression on all cylinders, I would look at fuel pressure and engine computer codes.

Buick rendezvous misfire issue


Since you changed parts, you have covered some possibilities. On the spark side, the Crankshaft sensor and( if equipped) the camshaft sensors give the information for the firing Pulse.

A wet connection on either part can certainly cause a misfire. There is also the possibility of a fuel injector misfiring due to a connection or bad ground on the injector during damp weather.

Sometimes if you get lucky you can see spark jumping on the motor by operating the engine in the dark. Mist the engine with a spray bottle of water to see if you can induce a misfire, if unsuccessful with normal weather conditions.

WD 40 often cures moisture problems.

Please rate my info.

Ck engine light is on and miss fire #5


There are few possibilities that can cause engine misfire issues. It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

WHAT IS THE FIRING ORDER FOR A FORD FREESTAR 4.2l V6?


The spark plug firing order is ( 1 - 4 - 2 - 5 - 3 - 6 )

The engine cylinders are 1 , 2 , 3 from front to rear on the passenger side of the engine and 4 , 5 , 6 from front to rear on the drivers side of the engine

The coil pack towers are numbered 1 , 2 , 3 from front to rear in the row nearest the passenger side and 5 , 6 , 4 from front to rear in the row nearest the drivers side


hope this clarifies the situation for you

My 2000 f250 5.4 gas motor has a miss and sputters under excelleration. I changed the plugs what else can it be


It's possible the miss and the sputtering are two separate problems. Bad spark plug wires can cause a miss and poor performance. Sputtering may be a fuel delivery problem - anything from a clogged fuel filter to a bad fuel pump or dirty fuel injectors. If your fuel filter has passed its recommended service interval, or if you have heard of bad fuel problems in your area (my area had an incident a couple of months ago), change the filter.
The most efficient way to check the wires is to measure the resistance if you have a multimeter. Radio interference suppression wires should measure approximately 1000 Ohms, with the exact amount depending on length. Metal wires should measure less than 1 Ohm - very little more than you would get if you shorted the two ohmmeter probes together. (If you need more information on using a multimeter to read resistance, I can write that up for you.) Note: check just one wire at a time so there's no chance of mixing up connections. If any wire fails to produce a reading, or it won't read unless you bend it just right, that wire is broken. If any of the spark plug wires has damaged insulation, especially burned spots, change it. (Sometimes you can find bad wires by looking under the hood after dark with no lights present - you may see corona discharge or sparking around the bad spots.)
With the problems you are having, I would be surprised if you did not have your engine service light coming on. Get a readout of the engine computer error codes. This can save a lot of time and money trying hypothetical solutions. (I have listed the most common and simplest items, but there are a number of other things that can cause your problem.)

I have a 2004 f150 with a 5.4 that bogs down around 2500 rpm and doesn't smooth back out until it gets just above 3000. Any tips on what is causing this?


I've seen two concerns that will definitely cause this concern. The first suggestion would be to replace the spark plugs if the vehicle has 50k or more miles. Ford originally stated that the original plugs would last 100k. It was later suggested that they be replaced at 60k. I've fixed several trucks by simply (or not so simply) replacing the spark plugs. Use caution, the plugs may break when removing. A symptom of this concern is as you stated but also on wide open throttle applications. the vehicle will bog down and sputter, then finally smooth out. A spark plug concern will typically not throw code because the computer monitors changes in rpm and is relative. If all cylinders aren't firing correctly, the computer doesn't know any different and does not store a code. Also, depending on the mileage, check the fuel filter.

The second concern could be the intake manifold runner control. This is used to modify torque and is located inside of the intake manifold.

Good luck, if you can't leave four thumbs up, please ask for more information. Have a great day!

2007 Pt Cruiser I Changed spark plugs 2 weeks ago Bosch Platinum +4, car is non turbo 2.4 ltr engine. within 1 day engine light on cylinder 1 miss fire, read on the net changed plugs to Champion RE14MC...


remove the plug from the #1 cylinder, and install it into the #2 cylinder , and put plug from # 2 clyinder in to #1 plug hole, connect plug wires, and start up vehichle, and if computer shows misfire on # 2 cylinder , then you have a bad plug, possibly porcelin insulator could have a hair line crack in it, hope that this information has helped you.

A cause for that would be an oxygen sensor getting wet, the one on the inlet side of the catalytic converter.
