Can anyone please advise the correct idle speed for an automatic 9000 D direct ignition turbo engine. I have only owned the car for 5 months & recently put it in for service at the local SAAB dealer. When I bought the car it idled at approx 750 R.P.M.which gave the car engine braking I.E. if you took your foot right off the accelerator for about 1 second, the car would change down a gear & slow up. Since the sevice & 2 extra attempts to get the same performance, the car now idles at approx 950 R.P.M. & when you take your foot off the pedal you just coast on forever - just like an old Ford.The mechanic involved has supposedly just completed an additional training course on tuning SAABs.

Any help appreciated

Welcome to SaabCentral, Richard.

You don't say which year, but with DI I'm guessing you have Trionic engine management. In that case, it should be 850 +/- 50 RPM. I haven't got the spec. in front of me for pre-Trionic, but I think it should be similar or the same.

Idle speed on Trionic is not adjustable. Not sure whether it is for earlier DI cars. A possible cause of incorrect idle speed (or idle speed being slow to settle) is an idle control valve in need of cleaning. See here (http://www.saab9000.com/procedures/fuel/iac.html) for the procedure.
