Can some one please HELP
My Disco sounds like it is only running on 7 cylinnders and when under a load it pings like a pig. It is running on LPG the engine has done 84k and strats 1st thing in the morning A1, and when warm. I have chaqhed the timeing (dissy), New spark plugs, New leads, New cap and arm and coil. I am startting to think that it is internal, IE valve or cylinder. I would like to do a pressher chaeqe but do not have the tool. Any iders
