I did not get a notification, did you pick up your PP deposit? Anyway, it's a bit of a long shot - but I remember a thread on the NG BB at saabnet that suggested the Throttle Position Sensor can create similar symtoms. Failing that, it may be picking up air interally. This can happen when one of the circuits is bunged up with fines from the clutch packs.. How it can be expected to work right in the long haul without a filter is still beyound me - but who am I to second guess the slappy gang over at SAAB on this one. -- Radio Free Dexterdyne Top Tune o'be-do-da-day Rocky Horror Picture Show - Over at the Frankenstein Place http://www.dexterdyne.org/888/110.RAM all tunes - no cookies no subscription no weather no ads no news no phone in no sign up required - all the Time
