Hi, i bought a range rover 4.0 se 98 with lpg last week. after getting it home i noticed a solenoid passing gas, so decided to get it changed and have the system checked out...I had the system checked out and solenoid changed. I need a new lamda sensor?? He quoted £120, is there anywhere better? Also...whilst driving on lpg, when i sometimes slow down for a juntion and roll to a stop, the revs drop right off and sometimes stalls!!! this has happened twice now and tarting to be embarrassing. Can anyone help??
