SOURCE: #4 CYLINDER MISFIRE

Hi the most likely fault would probably be head gasket, it maywell show no other signs of fault as it can blow into next cylinder.
Have a compression test carryed out and all 8 cylinders should be within 10% of each other.

SOURCE: Engine misfire...

First off what you want to do is see if the coil is keeping fire to the cylinders. If so is the fire blue or redish/orange. If it is blue then its not a firing issue. If it is red then you probally need a new coil. Now if you chose option A then check the spark plugs and make sure they aren't fouled out. The way to determin this is that they will be black and smell like gas really bad.If not then check the spark plug wires and make sure they are not ripped, broken, cracked, or show any signs of failure, If not then make sure it is getting plenty of gas. If not then it is either the fuel pump or the fuel filter. If it is a fuel injected engine then make sure the injectors are all working properly. To do this you will probally have to bring it into a shop and have them check. If it is a carberated engine then manually chock the carberatur by holding the top flutter valve closed for a second or two. If the flutter valve gets covered in gas real quickly (in less than 2 seconds) then it should not be a problem with the carburator. If you are still haveing problems with it after checking all of this then give me a shout back and i will see what i can do.

SOURCE: one cylinder misfiring. checked injectors and tappet clearance both okay. Suspect poor compression on cylinder number one. Defender 110 tdi

I take it you have also checked plug and wire. If so could have carbon build up causing valve sticking or camshaft rolled lobe or bad lifter, bent pushrod. This about covers all other possibilitys

Why is there a cylinder 2 misfire?


Check these three things in the misfiring cylinder: spark, gas, and compression. One of them is wrong or missing. For spark check the spark plug and wire. Make sure you have spark on the plug wire, a strong blue spark. For gas, the fuel/air mixture may be wrong. Does the fuel injector pulse, putting gas into the cylinder? Possibly you may have a leaking injector or a clogged injector.

If gas and spark seem okay, you need to check compression in the cylinder. Low compression will cause a misfire. If compression is 20 or 25% lower than adjacent cylinders, that could be causing a misfire. For example, say numbers 1 and 3 cylinders had about 150 psi compression. 80% of 150 = 120, so if cylinder 2 is 120psi or less, that could be setting the misfire code. Low compression can be caused by valves not seating well, or bad piston rings, bad head gasket- something in the combustion area of the cylinder is losing compression.

Random multiple misfire P0300, P0302, P0304 on 2006 Kia Rio


A competent mechanic will check all probable causes associated with these DTC codes.
Code P0300: Random-Multiple misfire detected. Probable causes:
1. Vacuum leaks, damaged hoses, or improper routing
2. Fuel contamination
3. Ignition system - Ignition module, coil, spark plugs and wires
4. Fuel system
Code P0302: Cylinder 2 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system
Code 0304: Cylinder 4 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system

Be sure the invoice enumerates all of these probable causes as having been checked. Also, some of the replacement parts installed earlier may be faulty.

I have a 2002 Jaguar X-type. The check engine light came on and it has been acting jumpy/shaky. I recently took it to be diagnosed and the codes I recieved back were P1314, P1316, P1111, and P0302..What do...


All fault codes can be checked out at http://www.bluejag.co.uk but here are the results for some of yours. You can ignor P1111. Looks like a faulty plug or coil pack cylinder 2

Fault Code:- P1314 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire rate catalyst damage -bank 2 NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- ECM Default:- Maximum engine speed reduced


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.


Possible Fault:- Cylinder compression low Worn camshaft / broken valve spring(s) Fuel delivery pressure (low / high) Fuel injector(s) restricted / leaking Fuel injector(s) continuously open Fuel contamination Fuel injector circuit fault(s) (Injector DTCs also flagged) Spark plug failure / fouled / incorrect gap ECM to ignition coil primary circuit fault (Cylinder misfire detected DTC also flagged) Ignition coil failure
Fault Code:- P1316 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire excess emission NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- none


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.

CHUGGING ALONG WITH FLASHING CHECK ENGINE LIGHT....???? 2002 FORD WINDSTAR WHERE TO BEGIN


A flashing Check Engine light means you have a ignition Misfire, start by replacing the spark plugs and spark plug wires, one or more is defective. If you have a electronic engine control fault code reader the cylinder or cylinders that are misfiring will set a fault code, the codes are P0300-P0306, the last number being the number of the cylinder ( cylinders 1-6) the computer has detected a misfire in.

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,

WHAT IS THE CAUSE OF THE PO301 CODE?


The error code p0301 ,This code is related to misfire.The cylinder is misfiring. p0301 this is the indication of cylinder number 1 ,that is misfiring.If the code comes up as p0300 this is the indication of random misfire from all the cylinders.But in your case its indicating p0301 this is indication of cylinder 1 misfire.Check cylinder 1 and replace the faulty cylinder 1 to clear the fault.The spark plugs and the wires connecting to spark plugs also needs to be checked. Keep updated with any more query.Thanks.
