Picked myself up a 1997 Peugeot 406 GLX with the 2.0 Litre Engine in it 61,000miles £900!. Been fitted with a Zavoli Multipoint LPG kit and Matrix Injectors, Runs very well on LPG, there is a little bit of 'pinging' on idle on both petrol and lpg very slight you can just feel it through the cabin and it does it and the engine makes a slight change in noise. Suppose it could be the spark plugs being fouled or something like that. It is due a service any tips as to what Plugs and HT leads I should use on the 406? what the spark gap should be for optimum preformance and reliablity on LPG and Petrol? And one final question can I use a K and N 57i Induction Kit on my 406 for a little more omph without it affecting the LPG kit? any knowledge welcome oh yeh installed flashlube in the engine just for piece of mind.

NGK plugs all the way, as they are better suited for dual fuel... not sure of the exact model though, best to check with a local LPG installer. You mention, that there is idle pinging... might be an idea for them to do a service on the gas system as well. Mine costs about £40 and thats the filter and plugs all included.
