I've got a Rover 416si N reg, and over the past couple of weeks the revs don't always drop back down to tickover when I stop at the lights or slow down for corners etc. I have to blip the accelerator up a bit to "clear" it, and then the revs drop back down. It's got worse this week, and I've had to change the way I slow down due to not allways having engine braking to help slow down with.
Any ideas what might be causing the problem?
Thanks a lot. Garry
