Hi Guys

I ve a problem the car is vibrating on idle and there is a high consumption of fuel which affect the air con compressor that cut off when the car come to a stop so the rpm drop as the compressor is turned off for a second and then the compressor reconnect and the rpm return to it's normal case.

Sometimes the belt is making some noise like it's snapping when i turn on the air con.

please help me...

sounds like you might have a air leak to find this spray wd 40 around the injection pipes and air intake and inlet manifold if you have a air leak when you spray the wd 40 over the leak the tick over will steady .this is because the wd40 acts like fuel too the engine to balance the extra air that is being sucked inor you might just have a split air pipe

OK i will try the wd 40.

Thank you Bill

I replaced the air con compressor last month when i checked the belt today i found that the belt tensioner is vibrating, does it need to be replace?

and the belt had done 30K kilometres
