After starting with cold engine the engine cuts out on idle.

This happens only in the first 5 minutes. Sometimes I need to start it a few times. When cutting out it goes very slow from about 1300 rpm to zero.

Had anybody the same experience with a IEC 4 system?

Could it be the idle valve, lambdasensor of temp sensor ?

Any advise is welcome!

Thanks.

 

Forget lamda and temp sensor, most likely culprit is sticky iscv.

My ISCV sticks every now and again on my RS 2000, it does the opposite though, idles at around 1500 rpm

Take it apart, give it a clean and a light oil, that should sort it.
