For a while now my car has had a problem where there seems to be alot less engine braking than on other cars ive had. When im driving along at say 55mph il let off the throttle and the speed will stay at 55mph for a couple seconds before slowly reducing. Now ive noticed that the problem is worse when I have the air conditioning on and when it is the revs will slightly stick in between gear changes. Also today after a long drive I stopped at some traffic lights and the car tried to stall and then the revs shot up to 1400 and then back to 750

Also the car idles quite low at just under 750rpm which picks up to about 800 with the a/c on.

So what I need to know is has anyone else had this problem, what caused it and was it expensive to fix? Cheers for any help.

The car is a 1999, 1.8 petrol Focus.

 

sounds like you may have an air leak?you got any management light on?

 

is the engine haunted? I have heard it in the past where by the engine can start on its own accord and some have even been known to talk to the driver. There are good and bad ghosts so it depends on what voice you hear... if it is an angry quite offensive voice then you have got a bad ghost but if it is a nice voice then it is a good ghost

 

It'll be the VSS, very common on zetecs as I found out last week. Google it, its an easy fix apparently although I've still not sorted mine!!
