started on project "diagnose misfire" today

changed the plugs from NGK iridium to plain copper ones and gapped them at 0.6

cleaned the AFM and foam in the pod filter

tried to change the fuel filter, but couldnt get the bastard out :(

if what you have done hasnt solved the missfire, take it for a drive, do a few ks and then pull the plugs out one by one and check them

if they are being fired properly they should be blackened

if you find one that looks like its brand new or not as used looking as the others, then chances are the coil pack for that cylinder has flogged out

you will need to replace that one

thats what solved my misfire problem

changing the fuel filter is a good thing to do.

did you have any success with project diagnose missfire?

Haven't taken it for a drive yet, so I'm not sure.

Got all the hose clamps off the fuel filter and then couldn't get the hoses off, so had to turn back.....got any tips?

all the plugs I pulled out looked about the same colour.....greyish....so it looks like the mixture is OK

Couldn't see any obvious cracks or anything in any of the coils, but that prolly doesn't mean much.

I'll take it for a drive later and see how it goes....if it's still missing I might wind the boost down a bit, coz since I fitted the dump and FMIC it seems to max at about .8 or .85 BAR

thats how i got them loose, usually over the years they have melted a bit and end up stuck on

yeah...I think that's what's happened to mine....makes you wonder how long it's been since the fuel filter was changed :(

    • Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.
    • Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.
    • Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?
    • 1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
