Hi all, after continuous trips to the garage and multiple sensor changes my 62 Navara is still playing up!!.......no matter whether its warm or cold everytime i change gear the revs don't drop down quick enough. I've been told it was this sensor and that sensor which have all been changed....i've even been told its a characteristic of a Navara....RUBBISH...it didnt do it before....pulling my hair out now. Has anyone had a similar experience?
