Brutewrench Posted May 3, 2004 Share Posted May 3, 2004 Hi all, I have been working on a 1990 Legacy (AT 2wd) trying to solve a flatness and rough running at part throttle. I pulled off the air inlet assembly from the intake manifold and cleaned significant dark residue from it. I noticed a needle valve on the top of this unit that seems to affect idle speed and smoothness and was seeking information on how to properly adjust it. I marked it as I removed it and reset it to the same position for the moment. Since it still was not running perfectly, I did the ECU read with the black connector. It showed an oxygen sensor failure (32). Then I did the driving test using the green connector. It did not behave like any of the articles I read on the subject. When I drove it, I got a 30 code - 3 long flashes that repeated. I replaced the O2 sensor. The car does run better, but not perfect. I can not figure out the best way to clear the fault code - the 32 is still coming up. I do not know if that means the car has another related problem or whetner it means that I just have not rest the ECU correctly. Thanks for any tips, Gary Quote Link to comment Share on other sites More sharing options...
