hi,
my disco 2002 facelift 4.0 v8 has a lpg conversion and is driving me mad!it has a random misfire and keeps putting the management light on.it has gone into what appears limp mode a couple of times,ie no power and 40mph max.so far it has had a new airflow,both coil packs,4 new o2 sensors,plugs and leads,throttle position sensor.
while better,it runs lovely but still puts the light on and occasionally misfires.various fault codes have come up,includingpo308,304306,302 ,cyl misfires,p1300,p0154,155 o2 sensors.
current codes today are po135,155,141,161,154 all pointing to misfires and o2 sensors.it has just had new sensors fitted.
yesterday it drove superbly but the management light came on and went off again approx. 10 mins later but with no obvious running fault.today it starts and revs but is virtually undrivable with the fault codes above shown.
i'm now running out of patience with it and am wondering what else it could be.it will put the light on running either gas or petrol.
any suggestions?
