audi coupe cold start??

[sox]

Hi all,

i have a problem when starting my coupe from cold.
The revs are so low on start up that if i were to take my foot off the throttle it would cut out.

when its warmed up its fine.

its 2.3i NG bosch KE 3 Jetronic inj

i looked for the aux air valve which can sometimes clog up wiv crap and cause a fault like this but there aint one

So any ideas...................?

acceleration enrichment sensor???

Seems like you need a new sensor.
