Car Forum / Saab Cars / October 2005S.O.S. '92 9000CS
Last couple of miles on the way home tonight I noticed a problem with my old faithful 9000CS 2li. Seems reluctant to pull in the lower gears. Kept feeling it might stall at the lights, not the normal smooth idle, but jumpy and eratic. Felt like it needed a good "fart" to sort itself out. Can't see anything tonight (it's pitch black in the driveway) and I wouldn't know what to look for anyway. Do you think I should I risk the 40 mile journey in heavy traffic to work tomorrow? What could it be? Could it be the dreaded ECU on its way out? The car's 14years old and done 150K. Any thoughts or advice much appreciated.

If you were DI - then you would want to start checking your TCS valve on the firewall and DI unit itself instead of ignition wire and coil. In either case, at that age and mileage - I'm betting it is the vacuum system and very probably somewhere behind the engine or in the Fender. -- Radio Free Dexterdyne Top Tune o'be-do-da-day Glen Frey - Smugglers Blues http://www.dexterdyne.org/888/046.RAM all tunes - no cookies no subscription no weather no ads no news no phone in no sign up required - all the Time AIC valve ? My '95 CSE had similar symptoms, most noticably 'cyclic' idling between 500 and 1200. Dismantle, celan, reasseble: all fine again (but valve is a pain to get to) > Last couple of miles on the way home tonight I noticed a problem with my old > faithful 9000CS 2li.

Your engine need a good clean out and then more systematic debugging.
