Hello, everyone. I have a 6bolt in a 2g. When i look at my log (ecmlink v3) my front o2 sensor runs at .2v and holds there. Then will jump right to .8v or .9v. It will hold at that voltage for a while then back down. My question is, is this normal? I hear the engine load change when this happens. Also the idle(rpms) changes when this happens. Thanks for any info. I may be able to post a log tomorrow of it.
