Title: Ed 30 High revs at start up?
Post by: galaxie500 on May 20, 2014, 08:01:43 am: My 75K mile Ed 30 is often exhibiting very high revs on & after start up which then settles back down to normal idle shortly afterwards. This seems to happen usually when the car is warm but it has occurred cold too. What should I check gents? It had a PCV last year and pretty sure the DV good. Is it a fuelling problem?
Thanks.

mine normally kicks off to around 1100/1200 on cold start and settles to around 800.

this is normal unless your revs are severely higher?

Post by: galaxie500 on May 20, 2014, 11:16:30 am: Thanks for your reply. Annoyingly the revs shoot up to 2500 revs, which can't be good on a warm engine let alone one starting from cold.
Any other ideas?!

Of course a better starting point would be a diagnostic scan, but you know that ;-)
