Ive just got a (51 plate) 147 1.6 with 84,500 miles over the weekend. The car was running fine and done around 200 miles. Now today i was driving it to work and when i came to a stop the revs dropped slowly and the car cut out and the funny thing is is that when it cut out the ignition lights didn't come on but it did restart first time. i did look it up on here this afternoon and i see some people say to give the throttle body a clean witch i did as that was a bit covered. On the way home it was idling at 750rpm and didn't cut out. So all i really wanna no is 1 is that idle about right and 2 if not what els could it be?
