Try premium fuel to see if it goes away Posted by Caarma [Email] (#592) [Profile/Gallery] (more from Caarma) on Mon, 29 Jan 2007 14:00:23 In Reply to: Stalling and sputtering at start ('06 9-3 Aero), cptab, Mon, 29 Jan 2007 12:12:10 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I switched to mid-grade once on my 9-3 SC 2.0 T and it had a little rough idle for about 10 seconds. I have since gone back to premium and haven't seen this happen again.
These engines are tuned to work optimally with premium fuel even though they can adjust to lower octane and the transition in the tank that has a little of both might confuse the engine computer(?).
