my 1995 range rover is running normal then cold, normal then cold but generally cold. when this is happening is makes the heater run hot/cold too, which is steering me away from a faulty thermostat switch. this is the case for both petrol and lpg. it doesnt seem to be affecting the performance either hot or cold, but its getting chilly!
i have changed the thermostat and bled the system twice to no success. i recently changed the leads and plugs but have used ngk v groove plugs (they were free) gapped to 0.6mm. before i was running ngk bp6es, could this make a difference? everything else i have changed has been like for like ie leads etc, this problem has only arisen since the work was done. any ides?
