Idling problem 930 -77

[Jocke]

I have done a searching in the forum but havenīt find any similar problem.

Yesterday when I would go for a little drive the engine didnīt start so I start checking both the fuel and ignition but I didnīt found anything wrong.

Little later I try to start it again and this time the engine just sparkling a little bit.... When engine finally running it was idling about 400 rpm, so I push a little on the gas-pedal and then itīs running OK.

A few hours later I start it up and the idle was nearly 2.000 rpm, after that I have check all vaccum-pipes (I think at least), but the problem still remain.

Could it have something to do with the earlier problem when it wont start?

I now it could be the W.U.R or something but I dont now how I checking that.

Please I need help real quick. (the summer is barely over here in Sweden)

If I start the engine without the Air-Box the engine idle as 900-1.000 rpm.

And I dont think itīs the Airfilter because if I take it off the idle is still running high, but as soon as I remove the hole Air-Box the idle is normal..

Strange...
