Hi all

I have started using my 944 S2 for the school run out of necessity as wife taken on more work.

I have noticed that the cars engine after a third short journey hunts wildly.

This will recover after a short period of holding the revs at 1000 rpm.

It always fine for a couple of starts then as above.

Any advice would be great.

I'd check for air leaks, the pipe work is getting a bit old these day & starting to crack up.

Had a similar problem on my 91 s2 discovered it was the idle control valve sited under the intake manifold
When its running uneven try tapping the unit a couple of times, if the engines evens out , strip the unit out and give it a good clean out or replace it

My S2 was the same, cleaned the ICV out with injector cleaner and it now ticks over as it should.

Begger to get off and give it a good clean. I used thinners, soak avoiding electrical contacts and finish with brake cleaner
