Help: o2 sensor

I just replaced the o2 sensor in my gvr4 and its acting the same way. It idles a bit rough, and feels like its not getting enough fuel. Once i get into the higher rpm's and boost it, its great. Its low RPM's and the get go that is sluggish. When i do a data log on dsmlink, it doesn't seem to be reading correct, and sometimes not at all. It has gone down to .08 volts. Any ideas or solutions?

Check the secondary ign system. Could have plugs going bad or wires.

 

What are your fueltrims reading?

I had the same issues, turned out to be a bad sensor ground. Re-ran a ground and all was well.
