Hey there

I posted a few days ago that I was having trouble with my idle on my MY96 WRX STi. It was idling around 2000 revs and seemed to be 'hunting' all the while. This cleared its self so I just put it down to moisture and the cold weather!

This has now started again at higher revs, its fine up to about 4000 RPM
and then it starts doing it again. I don’t know how to explain it but you can feel yourself moving back and forwards?! You can also see the rev gage going up and down very slightly.

I checked out all the error codes and nothing came up except some historic ones about the ICV and the boost solenoid. But today the Check Engine Light came on, I checked the code and it was 32, which as far as I know is the Oxygen sensor.

The plugs seem fine when I checked them and the coil packs also looked fine. So could this be the oxygen sensor causing all my troubles or not? I thought maybe a coil pack was breaking down?

Thanx

Have you cleaned the solenoid wayne ??????

 

The boost solenoid? If so yes cleaned that along with the ICV.

Thanx

Now some on here have had the problems you describe and replaced the lambda sensor and it runs fine but other cases it hasnt cured the problem, needs replacing anyway bud so give it a whirl.

 

well i've got one on order so hopefull should be with me when i get back from my holiday! Hopefull that will solve it, but knowing my luck it will be something else!!!!

Thanx
Wayne
