I received an 02 sensor spacer from Motoring werks, and it did not get rid of my check engine light I got from the downpipe. I was trying to call customer service but they never seem to pick up, I was wondering if Installed in the wrong place or something, I installed it on the secondary outlet where the 02 sensor goes, not the downpipe. Would it be that i should have installed it on the downpipe ?
