    Hi all After a bit of tinkering today found that the backboxes on my P38 4.0 (LPG) are pretty Knackered. Had a quick look around online, would love a full stainless system but too much moolah. I found some standard stuff on Ebay and then came accross this which is cheaper than...

    P38 4.0 LPG - Misfire Under Load on Petrol and Gas

    Hi What do you mean by sequential LPG system? So does the MAF sensor get affected when running on both petrol and gas? Is there anyway i can test the MAF sensor? Will removing it completely give me any clues? Thanks
