First post!
Just bought myself a 4.6 v8 range rover with LPG conversion. Got it at a VERY good price as it has suspected head gasket problems? went tonight to look and to me it seems to have ignition probs? you start it up and it runs like a dog, if you try to rev it it very slowly revs and tries to die. Im thinking poss coil pack problem or may timing problem? Anyone got experience with them or know of a common fault? It has has plugs and leads already by the looks of it. Cheers
