You sure it's nothing as simple as a bad plug cable or a coil pack since you are convinced it's a misfire?
going to try and get the inlet properly off tonight and pull the plugs out properly
.
I presume you have followed everyones advice in the last thread and that problems is solved?

If so you havent upset anything electrical in the above process thats causing 'this' issue?
Still here somewhere........
since fixing the boost leak my fuel consumption has gone up and the responsivness, but the hard wire will be another test to do.
i cant see what i could of upset, hadnt opened the bonnet for a week or so, not been through any big puddles...
check spark plugs and leads tonight check the gaps etc, give them a clean if needed, check the leads for cracks...
then try a hardwire test on the fuel pump
Other possibility is that your lambda sensor has failed?
Running rich / lean - misfiring, etc?
Could just be piston slap at low RPMs and under load from the brakes?
doesnt sound or feel like piston slap, not tinny enough if thats the right way to describe it
Have you tried sticking a screwdriver on the block yet, mate?
Should tell you a lot.
Is it possible you've just got a shanky engine mount? Seems weird that engine is rocking left to right when it's rotating front-to-back?
Did you check the plugs and leads last night. You need to get that fuel pump hot wired as well to rule it out.
no didnt get any space in the workshop last night, but tonigh i hopefully will, gotta put new pads on again
Have your engine mounts ever been replaced?
Mine was much smoother after I replaced mine.
1999 Mitsubishi Lancer Evolution VI Tommi Makinen Edition
right, some updates with inlet off
first of, leaking rocker gasket *sighs of relief*
rear bank inlets quite oiley compared to front inlets
first spark plug, driverside closest to wheel....water ingressed white lead
middle spark plug-loose wasnt tightened up at all, didnt even need ratchet to under, full of oil
third spark plug pass side- relativly fine
the middle and the pass side one, both have the white exterior burnt with oil, water ingressed first one, not that bad.
of to get some spark plugs for it tomorow, currently has NGK R p**65?
screwdriver test prooved to be rear bank, front bank is running sweet as a nut, it just purs nothing there to even think about worrying about, no pinging. rear bank lumpier than lumpy custard, sounds dreadfull....however hopefully new sparks should fix it.....
only one casualty my engine bay has claimed another victim, the bottom bolt turbo to Y pipe has fallen somewhere into my engine bay, dont know where, thankfully not into the turbo, but where it is, its gone, is it normal M8 thread?
Also found that one of my inlet bolts was a m8, confused us slightly....why doesnt the 12 fit....the 14 is to big....is it 13...no its japanese no 13s on it... perhaps its floating around in the engine bay somewhere, along with my turbo bolt, 4, strut brace bults, 3 strut brace nuts, a billion washers, 3 engine cover bolts....and a small 10mm socket
If it's not had it's plugs changed they'll be PFR6J - Stock fitment.Originally Posted by pitslayer
If water's got into the leads it might be worth changing them whilst you're at it.
hmmmm thats them, im sure they were done when Don had it might be wrong though.
its only the one lead and on the outside, going to give it a closer inspection tomorow, give it a clean out with some electrosolvent, was no white inside the lead, just on the exterior
edit: got it wrong they have been changed, PFR6Q
So all these posts about problems, suggestions etc and you hadn't checked the plugs and leads?
hmmmm

Good point, well made...
the seal on the HT leads are very tight, the way the problem with oil in the spark plugs was explained to me, was that oil would come upwards and into the hole, and there is no oil ontop of the rocker cover, or on the leads, it was mostly because the middle spark plug wasnt done up
i hadnt checked the leads, because i didnt have anywhere to do it, where the was sufficient lighting and it was dry, i am not taking the manifold off outside, especially with the amount of nuts and bolts the engine bay has eaten....
either way still dont know if it is going to fix it yet
Whoever explained that to you got it wrong. You don't see oil on TOP of the rockers when it leaks into the holes - The plug seals (the ones that leak oil into the plug holes) are situated about halfway along the plug holes.
And so you've made the schoolboy error (as we all have) of assuming it can't be a certain part just because you think it's unlikely and/or don't want to take it all to bits to check - That's guarranteed to screw up your diagnosis and waste time!
I'd still suggest getting a spare set of leads ready just incase... They may look okay but you never know!
Kieran, when its cold and wet and starting to rain with no lighting, something in your mind should say "taking your car to bits right now is a bad idea"
besides that, the rocker seal is leaking at the back, where it joins the head, and the reason the one is full of oil, is that the plug wasnt actually done up
either way, I wasnt far wrong with my diagnosis
wasnt gearbox like suggested, and came to the conclusion, it was misfiring on the rear bank.....
granted it was a schoolboy error, but i really didnt fancy getting wet to try and find a couple of bolts i will have lost doing it in the cold, it was sensible not to, especially considering how many nuts and bolts my car has eaten...
but i still ask the one question, turbo Y pipe, bolts onto front turbo, the bolt is it standard M8, so i can put another bolt in there?
