If I hold it at say 3000 rpm for a bit and then let off, on the way down the idle will briefly stop at 1100 rpm then it drops quickly to 950 rpm for a couple seconds before it rises back up to 1100 rpm and holds. Also when I cold start it it will idle at 2000 rpm. Seems a bit high to me, isn't it?

 

I have seen the Dashpot cause some similar issues. It can be a little stiff. It is what the black hose with the little filter is connected to in that area. Give it a look over and see if that helps.

 

I'll take a look, thanks. This morning it idled up to 2500 rpm on a cold start and once it warmed up and the idle dropped it rose again to around 1500 rpm and then the rpm started going up and down rapidly between 1500 and 2000 rpms.

 

Check your coolant level

 

I'll top it off and see if it helps.

There's a video of it. And here's a video of my other problem.
