Changing spark plugs on saab 93 turbo 2.0

Sounds like DI cassette or spark plug fault. You need to connect a fault code reader to confirm

Sounds like the turbo. Have you ever changed the turbo? If not, I would bet on that. If you've changed it but have more than 60-80k miles on it, same.

first I would change spark plugs,any more problem change fuel filter.do not change wires you get worst which you have now.

by the sound of it you could have one or both of these problems.
1. a vacuum leak which is causing the car to over boost.
2. ignition fault which is causing the car to die.


1. look in the engine bay and look for small rubber hoses, check all you can find and look for cracks or splits. make sure you check the small rubber hose on the turbo itself.

2. you may have a faulty spark plug, coil pack, HT lead (depending on which engine you have)

1 is probably your boost problem
2 is your cutting out problem
i hope this helps

You should check out www.reliable-store.com they have info on repair, service, wiring diagram, electrical diagram, fuse diagram, torque specs,
troubleshooting, PCV, gear box, owner's/service/repair/parts manual, fault codes, error codes, etc everything on all vehicles. must check it out

Check for compression on the cylinder that is misfiring. If compression is good 100lbs or better than see if the injector is pulsing( you need a noid light for this). It could also be the spark so check and see if you have spark.

yes. switch to synthethic. you will feel a huge difference in performance, epecially at take off. you will also get longer life out of the engine. you can never go wrong with synthetic

No you can't.Internal damage will be done to the engine.Sorry to tell you this.

I don't have a source, but this guy might be able to help.
