Can egr cause misfire?

[Juicy]

Ok so looked it injector today, plugged in and wiring looks ok as far as wires go,
unplugged and put multi meter on the two prongs, read pretty much zero flickering,
took number 2 of and did same with engine running bad, voltage was around 5 volts.
so my problem is feed to my injector?

I've peeled wiring cover back to a point and can't see any breaks or rubbing marks,does anybody have any idea where this injector wire goes?

I was thinking about cutting connector to injector off and testing the 2 wires that go into it to see if it's a fault with connection in clip thing,
if that fails and it says no Fred to wires there then I will need to fit new wire at both ends (which is why I ask where it goes) then tape it to old loom

I would start a new thread if I were you. Having problems with my EGR valve and been advised that it needs calibrating. I can't do that with my diagnostics but it is only causing an idle misfire. Like you I have done spark plugs and lead's. When I disconnect the injector I get a misfire and it records it on the individual cylinder. I wouldn't be cutting cables until I got some advice. It could be as simple as a fuse not sitting properly. Unfortunately I don't have a great knowledge of auto electrics to help you further. If you get a resolution let me know if I find one I will give you a shout.

Just had a thought could it be the MAP sensor? A simple clean might do the job. I can't speak for the 1.2 engine but mine sits on the driver's side of the engine behind the timing belt covers.

I'm on phone so would take ages to srart new thread copy and pasting codes and stuff lol

Well wiring says no feed is going to injector number one so couldn't be map sensor?

Ok so checked ohms with ohm setting on multi meter over 2 prongs on injector and there's no resistance, so injector is buggered
