running like crap in closed loop ok so my pass o2 was bad so i replaced it with one of my old rear ones. now the mV are normal and read right inline with the drivers side. but it still runs exactly the same in closed loop. even just reving it at idle is like misfiring like crazy. when i disable closed loop it immediately runs good and revs fast. im gonna let the car get up to normal operating temp to make sure the o2 i put in is good, but is there anything else that could be causing this? im still on the stock tune i just removed the ses lights for air and egr. could anything else be the cause? if i cant figure it out im gonna get a new o2 with a new extension.
also in hptuners how can i disable closed loop in the editor so i dont have to have the scanner hookup up to drive my car. also how bad is it to drive it in open look all the time like this?
