    Engine Sputters

    2001 9-3 with 101K miles. New DIC and NGK plugs which were installed 1000 miles ago to address a constant check engine light which codes said were misfires. That clear it up. Also put in new fuel filter. Recently (the last 100 miles) the engine will sputter, has killed 3 times, but restarts right away. This seems to happen once a day sometimes in the first several miles of travel or after the car sits for a couple of hours after being run. Come to a stop light and it may sputter seems like starving for fuel, pump the peddle and it runs rough but clears up and is fine. Drives fine otherwise, after this event takes place it may not happen again the rest of the day. Sometimes it doesn't happen when first driven, sometime it does. I got a check engine light two times but the light was gone after the next restart each time and the shop found no codes in the system. They did find a poor vacuum line and replaced but the problem is still there. Any thoughts? Thanks Tom

    Wild guess is that the CPS is failing, but it's just a guess without any codes. Did you install a factory DIC or aftermarket?
