Saab: misfiring? 1996 saab 900 se Turbo, saab 900 se, saab 900

Question
Hello,

5 days ago my car was stuck in a the snow and from there on my check engine light came on. but the car was working normal. till a day ago when i was on the highway and all of the sudden my car decelerate and then accelerated again and then it did it again and again and then the check engine light started flashing till i pulled over and turned the car off and turned it back on , it manage to start moving but it seem like it was chocking, the turbo was at red line when i was pressing gas to the max but car was barely accelerating. and today i try to turn my car on it wouldnt turn on, starter is good it makes a flip but the car just wouldnt start,when my car was coming off the tow truck i manage to start the car up but then it died again. would this be a sensor problem ? spar plug problem? and also what kind of  sensor would it be o2? thank you!

  Inasmuch as it is noted in my profile that I do not have hands on experience with your model and year I can only offer general comments. That said, it sounds like you might have over-revved the engine during the snow episode and possibly damaged something related to the turbo. If your check engine light is ON, then you can "rent" a code reader from Autozone or if that is not feasible,go to <www.alldatadiy.com> to obtain a procedure for "counting check engine flashes" to determine the problem. It costs $25/vehicle/year to subscribe to that site, but well worth it, considering that, in my opinion, its the most comprehensive source of tech data for your (or any) vehicle.

  Hope this helps,
