Yes that is correct.There is also a coil that fires the spark plug for each cylinder.There are specific tests for each component so you can find out which part is bad.compression could also be an isue not likely if the problem came all the sudden.

What is order of troubleshoot for cylinder misfire P305?


Possible causes
- Faulty spark plug 5
- Clogged or faulty fuel injector 5
- Faulty ignition coil 5
- Fuel injector 5 harness is open or shorted
- Fuel injector 5 circuit poor electrical connection
- Ignition coil 5 harness is open or shorted
- Ignition coil 5 circuit poor electrical connection
- Insufficient cylinder 5 compression
- Incorrect fuel pressure
- Intake air leak
What does this mean? What does this mean?
Tech notes
The P0305 code means that the cylinder 5 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 5. If the problem persist more tests needs to be done to diagnose problem, see "Possible Causes"
What does this mean? What does this mean?
When is the code detected?
Engine Cylinder 5 is Misfiring.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation
P0305 Jaguar Description

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

Trouble Code: P0300

Multiple Cylinder Misfire Detected
Possible Causes:


Base engine mechanical fault that affects one or more cylinders.EGR valve is stuck open or PCV system has a vacuum leak
EVAP system problem or the EVAP canister is fuel saturated
Fuel metering fault that affects more than one cylinder
Fuel pressure too low or too high, fuel supply contaminated
IC control circuit is shorted to ground (an intermittent fault)Ignition system fault (a coil) that affects more than one cylinder
MAF sensor contamination (it can cause a very lean condition)TSB 03-06-04-030 contains a repair procedure for this code

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.

P0305 - Cylinder 5 Misfire Detected
P0306 - Cylinder 6 Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, The Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

When is the code detected?
- Engine Cylinder #5 and #6 is Misfiring.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation

Possible Causes:
- Improper spark plug at cylinder #5 and #6
- Insufficient compression at cylinder #5 and #6
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #5 and #6
- Fuel injector #5 and #6 may be faulty
- Intake air leak at cyli

Possible Solution:
- Perform Injector Service
- Replaced Spark Plug #5 and #6
- Replaced Injector #5 and #6
- Replaced Ignition Coil #5 and #6
