Title: 3.0 v6 ( lpg) misfire/lumpy tickover
Post by: idwal on 30 December 2012, 16:39:15
Hi - my 3.0 v6 with lpg (2000) has started to misfire.
it has a slightly lumpy idle and can be heard misfiring on tickover.
2 days ago it started to develop a stutter when driving - which would
cure itself after a few seconds,   sometimes it revs normally other times
stutters and then goes. (this is on both petrol and lpg).

I have done a paper clip test and,  with engine off is showing code 3-1
it goes through the 1-2 start up   then gives 3-1  and then  end 1-2?
31   No Engine RPM Signal - is this correct?

only other thing that has been done to car recently is I had a cat back stainless system
fitted which was bought off another OOF member  (sounds great)

can anyone suggest anything?

thanks
ken

31 is normal without engine running, start with basics. Check plug wells for oil/water, when was the last time the plugs were changed?

Good news Ken, try the Chip you already have, just needs a spare leg soldering to it from memory.
