Title: miss fire episode 3
Post by: Arpy on 07 December 2009, 20:41:00

car back with me mechanic had car for 4 days not one hesitation.
is it possible that when running low on on LPG it could cause misfire really grabbing at straws here.
ps the code reader off ebay can you reset codes.

I don't know what system your LPG is .. but on mine there is NO misfire when gas gets low .... it just switches over to petrol.. simple as that.. :(

Does the car run OK on petrol ?? If it does (or runs better) then suspect the ignition side of things .. LPG needs a bigger/better spark to ignite than petrol does .. so ANY ignition problems show much more on LPG than on petrol

its just annoying when fault cleared right outside maech door.
I have been trying to think what has happened on both ocasions and it was my lpg was almost out.
My system switches over as well and it missed on gas or petrol. its got to be a loose connection somewhere

If your particular LPG setup isn't switching over cleanly be aware that, if the petrol ECU sees a misfire on a certain cylinder it will blacklist it and stop injecting fuel until the engine is next started in order to protect the cat. It will store a fault code if this happens.
