Nissan Repair: micra 2007 acenta, air control valve, vacuum hose
Questioni took my car in for a service and since i got it back it uses more fuel and idles to high and revs climb and fall constantly
AnswerBryan,
I would take the car back to get it within adjustment. Now, since they cleaned things up when they did the tune there is a possibility that the car has a loose vacuum hose or the idle air control valve is out of adjustment. It could need cleaning along with the throttle body. But, first thought is a loose vacuum hose.
