Idle Problem

[Parish]

Having a bit of an Idle problem on my 406 1.9TD it likes to rev slightly high, sounds absolutly terrible, i cant give you proper facts on high much it over revs at the minute cos the rev counters on the blink, is there an adjustable idle screw or some sort of screw on the fuel pump to slow things down a tad

Thanks

where the throttle cable meets the linkage under the bonnet there should be an adjustment for the throttle tension. it will slack the cable so it wont as responsive on the throttle but it will stop it revving up at idle
