Code 17
 

I hope someone can help me out with this problem I have been having. I have been getting repeated code 17's for the past 6 months. I have had three o2 sensors and they all have done the same thing. I reset the computer and the car will be good for one month or about 9 drives and then I get the Code 17 again. Anyone have any experience. The car is a 93 R-1.

Thanks
Chris

I have this same code. Its (Feedback system for 02 sensor). I was told its caused by various things. One of them is Vacuum leak in intake system. So if you have a wierd idle. its probably a vacuum line off or a gasket blown out or needing replacement. I think its my Upper Intake Plenum Gasket. I have the Old paper one still. They switched to metal ones but somehow I ended up with the paper one on my Mana Motor.
