faizal Posted January 2, 2011 Report Share Posted January 2, 2011 hi I brought this ford focus 1.8 lx a couple of months ago and have had problems with high and low ranging ever since it was fine befor, i have had a new speed sensor fitted, new hose to the idle control valve and put on a diagnostics which showed a new throttle sensor was needed, which was then replaced.by the mechanic unfortunately i am still having the same problems, my car is idling between 200 and 600 rpm up and down, this is causing juddering and the battery light comes on and off. eventually the battery light will go off and the car stalls. It starts first time every time so i dont really knw the problem... please help Link to comment Share on other sites More sharing options...
