2007 saab 93
 

It just barely started happening. When I turn to the right it so stiff like I cant even turn that steering wheel. Than it'll happen to the left and than for some reason it'll just go away. I filled my power steering fluid up and it still doing it. What could the problem be and has anyone else had this happen to them?

And Lately the engine light has become on for some reason just in the morning and when I clear the codes it does pop up again till the next morning. The codes are P2135 and P1681. I pretty sure P2135 is the throttle body. I cleaned it all out last week with throttle body cleaner. But it never used to come on seance i got a new computer into the car last year.

So someone please help me I love my saab and everything about it.
