Missfire is back !
Guys
Having had my S70 fault codes read last week, the water temp sensor & air temp sensor were replaced. The fault codes were erased.
It then ran fine for 3 days on petrol, then I tried running on LPG, this was fine until this morning. It has started to missfire again around 3,000 revs on petrol & gas.
At the time of having the codes read it was running very lean as the adaptive settings were out. This was reset and was fine. I can only assume the adaptive settings have started to go awol again and are leaning the mixture off.
Is this likely to be because of a faulty lambda sensor ?
The original one has done for 132k miles, how long do they usualy last ?
I have spotted a titanium one suitable for an S70 bi-fuel on ebay, any ideas if this item is any different to the standard S70 unit my car has?
Item number 250215145835
Thanks
Jon
