ok i might be buyin a saab 1993 9000 CSE and the guy said it might need new o2 sensors. r they hard to replace on these cars i havent acutaly tookin a look at were there located. i dont no to much bout saabs im used to hondas. and how much to o2 sensors go for these cars. i belive its a non turbo and im pickin it up for 500 ux so i cant go wrong. the guy said hes not sure if it is the o2 sensors but just in case i wanna no more about them. thanx

 

the 1993 9000 cse has the 2.3 engine. the o2 sensor is going to be right infront of the engine when you open up the hood, just trace the the manifold and it should be right after the junction between the manifold and the exhaust pipe.
