Citroen Xsara Picasso misfire cyclinder 2

Usual suspect on these is the coil pack if it's a petrol engine,
which you didn't state.
Or if diesel possibly an injector fault.

Coil pack usually the favourite .

replaced with new coil pack. (120€)

still getting misfire. i think the next step is to switch around the injector cables and see if the problem switches to a different cylinder.

i wont do this until someone says its an option

Edit* Car is a 1.6 petrol.

Could check compression on that cyl and fuel filter ?

im reaching the end of my knowledge on this will check the injectors and test them. i dont know anything about compressions.

if its not the injectors. i will just have to bring it to a mechanic

well switching the wires is a bad idea but moving the injectors isn't.
Swap injector #3 with #2 clear codes and run it.
Retest it to see if the fault code has moved cylinders.
if it has you have a faulty injector.

^ Agree with above responder

ok i was away for a day,

came back and managed to test the injectors all are testing ok with an ohms tester set to 200 all are testing at 11.5/8

im wondering how to get the damn things out so i can switch them around they are on a rail below what looks like part of the air box

this is the image the top of the piture has the airbox bit thats covering the injectors, i cant find any images online or blow up diagrams showing bolts and such. later ill have access to a ramp so i can get under and behind the engine.

i cant wait till i complete this so i can update and show what was wrong and how it was fixed haha

you need to get the inlet manifold off to gain access to the injectors

yeah. took a few weeks and alot more money than i had but it is fixed,

after checking everything above and got the injectors out.

injector 2 was not working correctly because it was physically damaged. (alarm bells)

checked the cylinder head with a camera and noticed cylinder 2 was wet with moister. (alarm bells getting louder) hummed and haa'd and took the head off.

exhaust valve was melted. (alarm bell was chucked out a window and smashed)

so gaskets, oil, coolant, vavles, sealant, injector, tools. nm ratchet and a haynes manual.

winter tyres and wheels because i now live in germany.

and when i was looking into the engine bay i was humming and hawing about looking at the alternator...... well I had to buy a new alternator.

so the guts of a 1000 € but i learned ALOT.
