    Question Jumps at Stop Sign or Red Light

    Hi all,

    Need some help figuring out why my 2004 Saab 9-3 Arc Convertible w/1.8T wants to jump/hesitate when I am stopped.

    What I've done:

    1. Changed spark plugs using NGK brand
    2. Found a dead ignition coil, replaced that with OEM

    Not sure what else it can be. Any ideas will be greatly appreciated.

    Thanks all!

    Maybe borrow an OBD reader at Autozone and see if there are any codes stored?

    I thought only the 2.0 was sold in the US, not the 1.8? Currently, cars 25 years old can be imported into the US without meeting US standards. In Canada, it's 15 years. So a European spec Saab from 1996 can be imported easier to the US.

    Thanks Dave T,

    Yes, it is a 2.0T...I also have a Jetta that has the 1.8t. Sorry for the confusion.

    I found it was a failing MAF sensor. Replaced it....good as new.
