Ever since i installed this Bosch Universal o2 sensor i have bucking at idle. I am assuming this is linked to the recent P0300 CEL i been getting. This is the only thing i can think of.
 
Did you ever figure this out? My datalogger gets a max of .17 volts from the 02 Sensor so i assume is dead ... and on the same note it is misfiring at random (but pretty often) after my 6 bolt swap. No RM CEL however... runs great once you get going. It does idle like crap.

any advice?
 
A bad o2 sensor can cause a number of affects with a car. Youd be surprised how much it could affect the performance of a car. So yes, it can cause some random misfires. If your still seeing some volts from it i doubt it will pull a CEL. It wont be long before it does tho :talon:
