My saturn station wagon sw1 is acting strange. The check engine light comes on and blinks. When the car is driven it driver rough and is hard to accelerate. When its in park it runs like crap but stays on but when its in drive it shuts off. When I do get it to drive it was driving on its own with out my foot being on the gas. What does this mean do I need a new cat or what? Thanks
I need you to have your computer scanned for codes post the exact code numbers not code descriptions. Sounds like a vacuum leak possible a sticking egr valve. ALso inspect your pcv for holes leaks etc.
