What do I need to do, to tune up my 2002 Saab 9-3 Se 2.0 turbo?

it would appear that the oil seal on the input side of the turbo may need replacing. oil at the throttle body could also be from a faulty PCV valve operation. Have the turbo inspected by an accredited turbo specialist shop. if itr is a seal then there will be traces of oil in the hose from the turbo and in the inter-cooler pipes.

The simple one, you have a rear light blown. As for the check the engine light "you would need to get the code checked, that any Saab dealer can get by plugging a device into your car, and from there the problem will be narrowed down" sorry I cant be more specific but that light can come on for a multitude of reasons. :-(

sounds like you might have a problem with your throttle body. mine went bad and had similar symptoms. i had to replace.

i am the owner of a 2004 saab 9-3 that had the same problem. the car could barely make it up a slight incline.

after diagnostics, they determined that it was a faulty "pedal travel sensor" (engine code P1238), which cost $590. after labor and taxes, my total came to $747.53. yikes.

sucked to pay that much, but it fixed the problem.

your ecu went to limp mode. try to your saab dealer to have reprogram
