i got a 87 9000t, this thing idles way too high starts up at about 1500rpm and when worms up it idles at 1800-2000----i hate this, cant find any vacum leaks...what can it be, i'm the only person that has a saab around here in my area at least and no one knows about them,
i raced my friends 1.8t Golf that went [email protected] in a 1/4 i we ran from a slow roll, first gear he had me by 3/4 of a car second gear i was ahead half a car, as soon as i hit 3rd it was all over i pulled hard, also a 03" WRX from a 10mph roll, first,second, third,fourth gear...we let off at 115mph in fourth...aftermath...i was at his rear bumper...he has Full TurboXs exsaust from turbo back, and his ecu reprogramed to 02' version and little tuned...just thought id share this with you
ALSO DOES ANYONE KNOW how do i get rid of this crucial spiking, i wish i cold hold at list 13psi of boost all the time in 3rd all i can hold is 11.
my mods
2.5" custom exhaust cat back, no cat,boost cotroller, running spiking to 16psi.."little xylene in gas "

Please DO NOT bump messages to the top...
Someone will no doubt answer your message soon, but its a 4 day holiday weekend in the UK, and most of our experts have gone away....

My first try would be to give the idle control valve a clean...

Welcome to saabscene anyway!

You should have a cylindrical valve between the cam cover and the inlet manifold, 2 pipes on it, and a electrical connector..
remove it from car, and flush through with some carb cleaner or something similar..
Also check the throttle butterfly isn't coked up with carbon!
Hope my memory serves me correctly, as 9000's aren't my specialist subject!

The Idle control valve is liek previously said the cylindrical silver object with an electrical connection and 2 rubber hoses going to it.

Press the wire clip on the electrical connection, a lot of peopel have trouble with that!

Undo the jubilee clips on the hoses then slide the valve out of the rubber support.

Take the rubber hoses off of the manifold and the one on the throttle body. Clean them out as well.

Spray the valve with carb/brake cleaner then shake it, hopefully a load of black liquid will pour out. Keep cleaning it until its nice and shiny. Then a squirt of wd40 up it and a shake will do the rest. Stick it back on and that should be that.

If that doesn't sort the problem then squeeze the hose from the throttle body to the valve, if the revs now drop then you have a problem like a dodgy coolant temp sender, if the revs don't drop then you have a leak in the inlet manifold or an open throttle plate.

idle air controller, that is one of the wacked parts on my 87 9000 T as well, but i get low idle bout 400-800 up and down constant till warmed up, but still drops and stall sometimes...so i just roll start it right now till i install the new controller.
