it does look as though something is blocking your way as you can see one of the flat sides of the spark plug ,in the beginning I was thinking maybe the top of the spark plug with the spanner bit had come of as I have seen that before, I got it out with a stud extractor,
but you can definitely see the spanner section of the plug I would just get a long thin bladed screw driver and try to get what ever it is blocking it , also if you ever have a plug thread go in the head there are firms that would put you a coil in but that would mean the head off if you know what I mean.
 
See if a high pressure air line will blast the bits out.

Success. Turns out it was the bits of disintegrated plastic off the top of the coil pack. Don't ask me how it got down there but a combo of poking it with a screwdriver and an airline managed to get it out and the plug is successfully removed.

:banana:

Thanks for all the input!






(Although I managed to drop the mini ratchet whilst doing up the mini bolt that holds the coil pack in. No problem, I think, I'll just whip off that plastic sump guard and retrieve it :(. Ffs, Apparently even that isn't an easy job. :decision: Need to get it off anyway to do an oil change but will be checking out the other threads that talking about modding it. :violent: )
 
Glad you are sorted.
Sump guard takes 10 minutes tops to remove, once you get the hang of it!! ;)
 
I was trying to get just the black plastic out. Will get the whole lot off.

The plastic section is riveted to the alloy frame so it's all removed at the same time.
2 bolts at the front along with 2 screws.
2 bolts each side just behind the wishbone.
2 smaller bolts at the rear holding the plastic section to the subframe.
Job done. It isn't hard.
 
Sump guard is easy to remove, there are lots of pics. and threads on it.
I still prefer the 'Spareness it with a finder' method though. :D
 
Ok, so all done. 6 plugs replaced. All coils checked.

Still getting a misfire on cyl 2. Have swapped the coil with a different one and the fault didn't move so there's defo something there. Have also got a "misfire at low fuel level" which is odd as there's loads of fuel. Will have to start following the wires fact up and look for obvious issues.
 
possible injector fault had a 206 which had the same did the plugs and the coil and turned out to be a slowly dying injector once replaced good to go again

Cool. I guess I could shift one of the other injectors about and see if the fault switches cylinders?
 
Hey guys, gettin ready to tackle the P0302 my 02 KV6 with 110,000 Mi. Grabbing plugs, a coil and an injector to be safe and to not have to tear it down twice. From the looks of it ill need to remove the plastic intake which im going to remove, clean exc. Im i correct in removing it? Any preventative maintenance you guys would suggest while im in there. Anyone know the torque specs for when i reassemble and also what gaskets are involved. Multiple Manifold Gaskets or one? What luck have you had with Plugs??? Im wanting longevity as im not trying to do this often. Looking forward to feedback. Thanks

RE: plastic manifold cover, you don't *need* to remove it, but doing the rear plugs is a real PITA if you don't. Removing it is dead easy though and a good opportunity to do some other stuff. (You'll need to remove it if you want to get at the injectors for the rear 3 anyway and considering you've got a problem with cyl 2, you will need to..) I'm guessing you haven't done a compression test? Would be worth preparing to do that as well.

Afraid I had a cyl 2 misfire on near enough identical car and started in the same way as you. Plugs and injectors didn't do it :(

There are the three inlet manifold seals that can be replaced (for the upper inlets). Other things to check whilst it's off... does it rattle when you shake it? Pull off the VIS motors and check those. If it's full of oil... clean it. (Good luck...!)

You can also check other bits like IACV on the throttle body. Check the condition of the breather hoses that live under the inlet cover.

Word of warning - be really gentle teasing off the ht leads. The plastic that connects the lead to the top of the coil is really brittle plastic, and it's dead easy to break it. (As this original thread was all about!)

While I'm at it, worth also re-enforcing the point - when you're undoing the bolts that hold the manifold down (and also the smaller bolts that hold the coil packs in place) go easy (especially when tightening.) it's really soft alloy and can easily strip the threads.

make sure you slap a bit of copper grease on the spark plug threads before you put the new ones in.

I did it a couple of times, managed to bounce the offending item out from the under cover by banging it parked on a slope
