hello my dear jaguar lovers. I am from a country of Georgia.
unfortunately i cant fix some issue. I hope very much for your help.
Jaguar X-type 2004 3.0 with cods P0300 Random Misfire p0301 p0303 p0305,the check is flashing,engine speed drops,work 3 cylinders only,but at low revs the engine works perfectly.
I have already changedspark plugs, injector wire, injectors,ignition coils(used),fuel pump, air leaks are excluded... Next step will be ECM because I have not any other idea (((

there is no catalysts in the car, so I don't think about. the previous owner emptied the catalyst banks)))

P.S Sorry for my Bad English

 

As you have already changed injectors and plugs, this will not help you but for someone searching these in the future post #12 =

@artak there are also several posted threads where the wiring going to the back cylinders (1,3,5) has/have a fault from cylinders back to connection. You have to hand over hand check the wiring.

The least likely could be a bad CPS ( camshaft position sensor).

artak, before you go to that extreme, open the hood/bonnet and look above the left front wheel (as you are looking at the car, standing at the front bumper). You should see a bolt sticking out of the body with some wires attached to it. remove those wires, clean them all up, put them back down (in the same order you pulled them from) and see what you have then.

 

@I also changed this sensor yesterday, nothing has changed. Thank you anyway

 

@Thermo I hope this way will help me. thanks a lot
