Question about 2001 Chrysler PT Cruiser

1 Answer

Have codes: P0301, p1193. Have replaced the plugs and wires. Plugs are Champions. Debating on swapping the #1 injector with the #4. Just not sure about removing the fuel injectors. Hear pinging when accellerating. I had a blown head gasket that was repaired with a pour in solution. Any help would be much appreciated.

    Thanks a lot for your help. Just curious about replacing the head gasket with the timing and everything. I have did this on other cars but not with dual cams. I will need to get a manual. Thanks again.

Do not swap injectors

What would that prove?

Wires last the life of the vehicle
if they aren't mishandled

Plugs don't always fix a misfire

Study a little,especially OBD2 Systems

Now I see that you have something in there
for a head gasket,you can take it apart
& do the job correctly

So you already know the problem

    When you get the timing belt,you may get
    a diagram with it.
    A local repair shop with ALLDATA or Mitchell
    can print the cam gear & belt picture for you

I scanned vehicle obd scanner and got code P0304 misfire #4. What should I look for? To solve problems


Swap the #4 coil with #3, swap #4 spark plug with #2 and swap #4 injector with #1. Clear codes. Drive the car until it has a misfire code, again. If you get P0303, it's a bad coil. If you get P0302, it's a bad plug. If you get P0301, it's a bad injector. If you get P0304 again, it's a mechanical engine problem, like a burned valve, bad intake manifold gasket, worn cam, etc. or a wiring harness issue to the coil or injector, maybe even a bad computer.

did you check the coil it may be bad. for # 1 cylinder. if you can, just replace them all. then you will know everything is ok! but change #1 coil first to find out. try putting some injector cleaner in the tank, or swapping the injector from the #1 cylinder to the #2 and see if the code follows it and let us know.

P0301 - Cylinder 1 Misfire Detected.

Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder

Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

Being you have a heavy gas smell I would look into the injectors. If injector #1 is over producing it can cause a misfire. Test your compression and fuel pressure.

The MAF sensor is not the problem, these are cylinder misfires on #1,3 and 4. replace the #4 coil pack, #1 AND 4 use the same coil, replace the spark plugs and the wires.

2003 mercedes Benz C240 codes P0300, P0301, P0302 and P0303. Please, help me how to fix?.


P0300 Random Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
according to this fault codes first mark ignition coils
3 ---------------- 6
2 ---------------- 5
1 ---------------- 4
RB-------------LB
this right banks and left bank, please remove Ignition coils with lids and spark plugs from right bank and swap with left bank, if fault code change as
P 0304 Cylinder 4 Misfire Detected
P 0305 Cylinder 5 Misfire Detected
P 0306 Cylinder 6 Misfire Detected
You can Identify it's a faulty ignition system then next swap ignition lids from ignition coils be careful each coils have two lids one short and other long bit deference and when you remove and fix it to the car keep in mind correct order because each coil two different fire for two spark plugs don't mix up, if you mix it can create the fault code.if you detect any fault ignition coils or spark plugs or lids replace that and also whether god or bad recommend to replace spark plugs, find the right that's most important thing, if this way couldn't found the any ignition fault next step is check fuel presser, when the engine running fuel presser must be around 4.5 bar without engine running must be 4 to 6 bar if the fuel presser too low need to check two different things one is fuel pump other is fuel injectors, in this case you can swap injectors from right bank to left bank and find is the injectors leaking, if not leaking faulty fuel pump.is this information helped you? if yes please leave a comment,

Im working with a 2006 mini cooper and engine light comes w po304 code the car runs fine no misfire at all,plugs r new


Code P0304 Indicates a misfire in cylinder 4. The computer will notice these long before they get bad enough for the driver to notice. Check your plugs and plug wires for thightness. I know from expierence that "New" parts does not mean "Good" parts.

If you have access to a scan tool still.... swap the #1 and #4 plugs and if you still get a P0304 reading you know the misfire is likely in the #4 cyl. wiring. (A faulty injector could cause a misfire but it's less likely a culprit than the wiring)
If you get P0301 code after you swap the plugs.. then you'll know it's a faulty plug.


sorry for the long winded advice.

A P0301 code means that 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

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

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.

You are mis fireing on cyl 1 and 3 if you replaced plugs and wires and coil this is going to be a fuel injector issue or valve issue. See if you can swap the injectors with known good cyl. and see if it changes. Or have a shop do a fuel injector service on it to see if it helps. It may be to late for the fuel injector service.
