Cylinder 1 misfire after replacing spark plugs
2006 X-Type 3.0 V6 (Left hand drive)
Decided to do some maintenance on my car and replaced the Air and fuel filter and all spark plugs but afterward it misfires on cylinder 1 only, have a code for it and its severe enough to set another code for bank 1 cats being damaged, P1313 i think.
I believe cylinder 1 is the one against the firewall nearest to the pulleys?
It flashes the check engine light on take off and misfires constantly on idle and revving the engine but once I start driving about 35mph it seems to go away. Swapped the coil and plugs from #1 to #4 (the one thats easy to get to) but it still misfired on only #1..
Here's the bad things I think I did:
Used Bosch 4 tip uranium plutonium unobtainium plugs from pepboys but then why would that cause only #1 to misfire?
Also didn't replace the green intake gaskets but then again would that cause a misfire on more than just #1?
Any help would be appreciated guys, I guess I'll do a compression test on cylinder 1 tomorrow morning so that means I get to take off the intake manifold for a third time yaaaay
Also read in some other threads leaky injector could be to blame, this is my next area to focus on how can I check it? I was planning to use a stethoscope to listen to it activating
