Took TBE for a drive to see if it inspired enough confidence to go to lakes.
It failed.
rather thing.
-
So what have you done to it now... Poor thing ::) ::) ::)

Misfires again?

Misfires again?
Like a bitch. So bad its knocking my fillings out

So, new plugs, swapped coil PAC, no oil in wells ...
... And it still misfires. :-?
Wiring to coil pac? :-/. (and sucking eggs :( )
-
All the time, at idle, or only under WOT?
Does seem odd considering the recent checks.
-
It was under wot at the essex meet. Which is where the problem first arose I believe.
Seems to be getting progressively intermittently worse. No matter what's done to ignition system. 246 bank was the problem last I heard...?

Glad I wasn't driving :-X :-X ::) ::)
Actually... Doesn't matter.......... It's not my car :P :P :D :D

Yeah. Mines fine. :)

Actually, this started once it was lpg'd didn't it?
Wonder if the injector wiring is iffy? Only reason I drove it was to test the kit, and it played up then and got worse since.
Or is it my memory misfiring as well? :-/

Yeah, did start after the LPG went on. Shouldn't think it's the wiring... It took him long enough! ::) ;D But not rerally seen anything that points towards the LPG. Really needs to pull the fuse on the lpg or disconnect the injectors while it's got this miss to rule it out though :-? :-?
It's such a shame though because that kit runs perfectly on mine (and yours) so we know we've finally found the combination that works ::) Although I'm seriously considering trying a timing processor to see if there is any further improvements to be made ::)

Unless there's a very slightly trapped pipe less severe than I had. Although i'm sure he's narrowed it down to gas only or petrol or whatever.

Can that home made bit of loom be unplugged for a while?
-

Yep, and he can then run on Petrol for a while to see if there's any change.
Is the miss moving about or in 1 cylinder/bank? I wonder if the vapour hose is kinking when it gets warm and restricting flow? :-/ :-/
Still... Not a lot of point in us guessing randomly ::) ::) Reckon there must be a curry in my near future ::) ;D

This error - 0304 - only happened since I did the cam cover gaskets. It was at this point I put on a replacement (2nd hand) coil pack, as the old one had been soaked in oil, and was breaking up.
Misfire codes previous to this, I'm sure, were due around trim issues due to LPG.
I swapped the plugs over between 2 and 4 last time I took it apart, and the fault has stayed with No4.
Its present on gas and petrol. It seems to be worse in warm weather, but I suspect thats coincidental, given the air temps v engine temps.
My theory is:
Coil Pack (likely)
LPG loom
I'm tempted to try another coilpack to see how it goes....
-
I should say, when it doesn't misbehave, its great on LPG, with no lag or other issues. So once this misfire is cured, the next step is persuading the bloody thing to do corners.

I'm not entirely sure it can be done, but could you swap over the 135/246 coilpacks temporarily to see if the miss moves bank? :-/ :-/
Failing that I think you may have to bite the bullet and get a new one :o ::)
I think the LPG Loom is less likely as nothing appears out of place when running, unless one of your joints is dodgy? :P ::) ;D

I'll bring cp's to the lakes if needed?

Can't swap between sides.
Might try to get the original CP back in, though a couple of months out of the car has caused it to disintegrate further...
The joints are properly soldered and heatshrunk. Unless that has caused the wire at the end of the solder to go brittle, and only held by the heatshrink, its 10,000 times more likely to be the plugs somewhere (so at ECU - anything else would only affect petrol or LPG, not both).

I agree... I still don't think it's the loom though... Everything seemed spot on and nothing untoward was showing up on the AC software when it first started ;)
Mind you... Yours was hunting quite a lot on LPG, which mine doesn't do :-/ Having said that, it hunts more on petrol than mine does too :-?
Reckon it's coil pack(s) personally :y :y

Re-fit the old coil pack and use the boots off the newer second hand one.
-
While this is no real logic as it could be faulty anyway regardless.
the cp currently in TBE is off Albs breaker 3.2. Which had done 80k iirc?
It is in better nic than the one in my car currently on 67k, better than the one on my old car at 105k, and far better than the one on my silver irmscher elite with 137k. None have issues.
I can't help think the problem lies elsewhere seeing as Albs coil PAC appears to have had no effect. As I understand it? Has it? :-/
-
Breaker was on 133k Chris. ;) Ive mentioned it before but, if the coil pack from the breaker turns out to be a dud, let me know and I will refund you, or TB - not sure who owns it now. :y
-
Right, in that case we better swap with a known good one.
Can stick mine in it to eliminate or prove....?

Was thinking the same, although it's more likely to be yours as it's not going to the Lakes ;)
-

Well, I was half right ::)
I refitted the original, but didn't swap the boots, so its running the boots that have been long term soaked in hot oil. The CP istelf is in a real mess as well.
-
Took it for a 25 mile hiding. The engine didn't miss a beat. But now I've breaked the rather brakes. FFS.
Its never ending :'(
-
Nah, I don't buy the coil PAC theory then, if that's the case.
Intermitant electrical somewhere... Which bank is lean btw?

The facts are I only ever experienced genuine misfire (not trim related from poor calibration) on a single coil pack. And its always been pot 4. Thats why I swapped the plugs over last time to see where the fault moved to. It stayed with 4.
I am quietly confident that is the issue, but want to run with this one for 2 or 3 weeks to see if it cures it (or moves to pot 6 - that coil looks knackered) before splashing nearly £100 on a new one.

Ok, but offers still there. We may be up that way then anyway. ;)
Found my vac pipe to plenum loose today btw. :-[

If in doubt, get it back to the last known working config. :y
As for the coil pack, it really needs testing using a test plug (but I dont think TB has one).
-

Ah, shucks, does that mean I have to tip oil in the plug wells :P ;D
(but I dont think TB has one).
Assumption correct, Mr DTM. So having to go purely by symptoms and results. I'd feel more confident with the car if I could prove the CP was faulty. As it stands, no confidence to take up North on Friday.

Also, for the same reason, I'm taking the Rover to work tomorrow, as she needs a 4 door car tomorrow as she's give a lift to 3 blokes tomorrow.
-
How readily available are the DBW coil packs, if memory serves me my local stealer implied that GM ones are hard to get hold of now.
-
no trouble at all, either new from ebay often enough
or plenty of stock from the dealers
-
Any good?

Has Twiglet still got his coil packs ? :-/

Don't know, but I'm seeing him tonight ;)

I believe his car was a known good runner, and in fact it still might be ? :y
Might want to take trip up to see him myself in the not too distant future.

In TBE's defence, just been for blast in joshwyatt's car, that overshot on the same braking point as well ::). The brakes held up better than TBE, it was just the laws of physics, and trying to stop the best part of 3t

You need something lighter. :y Actually, perhaps that's a bad idea. ::)

I was saying, as we were wallowing around the lanes, imagine this engine in a lighter car... ...ie, an XK
