Hey everyone. I've got the 1999 9-3 Turbo hatchback, automatic. I'm having a huge problem, and that is that I'm getting 15mpg. I was getting ~21 before, but the MPG deteriorated over the last couple of weeks.
So I took it to my local shop, where they replaced the oxygen sensor. After that didn't fix it, they did a full tune-up and found a valve that needed to replace.
So here I am, a day later, and the gas mileage still sucks. Does anyone have any suggestions for me?
Thanks nick
What "grade" of gas are you using? Specifically, the octane rating would be good to know. Also, it would be smart to look at the fuel filter. Basic-level troubleshooting, I know, but you gotta start somewhere.
Did you change the air filter recently? Also, check for small leaks around the fuel injectors. Any evidence of moist gasoline is a bad leak.
Was this a Saab shop, or a corner garage? What was wrong with this valve, and do you have the old one?
What did the Tech-II computer tell them when they asked it what was wrong? If they didn't do that, then that's your first step.

How are you figuring gas mileage? Did you reset the mileage computer after the work was done?
Figuring mileage through the SID.. How do I reset it?

Check your owners manual. On my 900, I hold down the button that displays the mpg until it clears. Until you reset it, it will average all mileage since it was last cleared -- including mpg from before you had it serviced.
