Engine warning light on when idling/in traffic and code P2004 shows

[SCOTTP999]

Hi all

I have noticed recently that if I am stuck in traffic for a while/ moving very slowly through the traffic that occasionally the engine warning light comes on. No loss of power or anything.

After using the car a couple of times (next day etc) the light goes off again. I have a hand held diagnostic that shows P2004 -generic code. As I say- it never comes on through normal driving, only if sitting at a standstill for a while or crawling in slow moving traffic.

any ideas?

It's your IMRC is stuck, so more that likely the FSV

But, check all vacuum pipework, etc to make sure it's ok.
