Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Hello, my name is***** you for the question. Can you give me the year, make and model of the vehicle?
Thank you. Most of the time this is caused by a bad fuel injector on the #6 cylinder. These are a common failure. I typically do an ohm test of the injectors. That injector is probably way off. If the injectors are fine then it is more than likely the ignition coil. I am assuming though that the plugs have been checked and are fine. Most of the time only the injector will act fine at times. I would start there. Please let me know if you need more help.
You can test the injector if you can access the harness going to it. It is not easy though. If you can send the data I will take a look at it. You should be able to attach it here.
You have a misfire code for number 6 associated with the 1316 which is associated with a cylinder injector issue. Your catalyst code is because of the misfire. The misfire will affect the catalyst.
Yes, injector 6 is in the same place at the #6 spark plug. It is the left side front cylinder.
Sounds good. I will be off and throughout the day.
The best way to test it is at the injector. You can test it with the injector hooked up as long a you can disconnect the wiring to it in the wiring harness.
It should be 50-55 psi so what you are getting is not too far out of line.
The attachment will not open. Do you happen to have it as a PDF?
Thanks. These are pretty straight forward directions. There is nothing too special about this repair. Just make sure that you replace the gaskets too. If there was a lot of oil in there then I would replace the PCV system also or at the very leak clean it out with throttle body cleaner.
Once the manifold is sealed the only place that oil can come from is the PCV system.
No. Typically the injector fails electrically which will not cause a pressure issue. If there was oil in the spark plug galleys then yes, the valve cover needs to be replaced.
I wouldn't worry about that code right now as the injector can cause it.
It should be around 4-5 ohms. Compare it to the other injectors as they should not be too different from one another.
There is not an ohm value given for either of these. If it was the coil you would typically a code for that. Since Jaguar does not specify readings for this I would just compare the readings from one coil to the others to see if anything is drastically different from one to the other.
Electrically they all seem fine. It may be a clogged injector, but now I am curious about that oil in the spark plug holes. Was it a lot? If it was then that will cause an intermittent misfire.
Definitely fix that leak. That may take care of the problem all together.
