Just gave Jusme's 3.2 a check over with simiar symptoms and the spark plug gap was huge 1.8mm. Could only adjust as a temporary measure and advise replacement once we had some available so check the plugs
Twins opened up I presume? Or worn?

Although I know I put quads in it, which I'm told are not adjustable.

Cheers guys - Pre cat codes have been resolved since the addition of another pair of lambdas (Thanks again Albs).

I've got a funky feeling this is a water ingress issue.  :-\

Until Saturday, I'm clutching at straws to be fair - But it's invaluable to hear from the guys in the know!  :y


EDIT: Pre cat, not post cat - Sorry Chris - Typing before thinking, again!  ;D

Sorry, can you clarify? Lambdas replaced? Or lambdas relocated? ...to fix the pre cat codes 0420/0430


with the amount of 3.0L cats that have popped up lately,just fit them with relocated lamdas. Loads better, not as restricted as 3.2 ones.

Yes, extremely!

All I could do was a temp adjustment to get it running and prove the diagnosis

I noted that the twins have a thicker more robust electrode

Ironic the quads are for longer life, do we know how long these were in/miles?

And/or is the LPG accelerating the wear?

Which reminds me, I think the Bullet's plugs must be 50+k old, I must get some, as they are twins  :-[

PITA that my local dealer isn't TC, but I'm working on a solution :)

A bit of good fortune tonight - If in Ice Mode, the missfire dissapears, so any knowledge on that front would be helpful!

Bad fortune - A screw in the OSF tyre very close to the sidewall.  A 600mile old Conti down the drain.

FML!!

I'll have a look at the missfire issue properly tomorrow.  Hoping it's a coil pack.  Wish me luck!!

Am I right in thinking that twin electrode plugs are preferable on cars with a lpg conversion due to the wider flame front ?

Also Al, got any pictures of this ballast resistor and its position ?
