O2 Sensor cause Misfire My car's been acting wierd lately, it'll start fine, and then be sluggish.
The car will like bog down, and sputter. WOT is fine, which led me to think it's an O2 sensor. As it fits the profile, before the car is warm it idles ok (in open loop) and at WOT it's fine (In open loop).
I was driving to work this morning and the SES light started blinking, indicating misfires. Could this possibly be due to a faulty o2 sensor?
Rear O2s are deleted (with tune), front O2s are Bosche 13111s. I recently changed plugs (ngk-tr55).

Well, looking under the car I found my passanger side o2 wire dragging along the ground. I went by auto zone and bought another sensor, hopefully this cures it.
How's your car running Malco?

misfires can definately be a primary 02. i had an audi s4(i know its not the same but..) and you would be amazed at what just a primary 02 sensor can cause. misfires will be on multiple cylinders and all on that one bank if its the primary 02 causing it
I'll get it back from paint on friday or saturday, hopefully friday so i can throw my axles in saturday 
.
After the axles, i need to investigate an SES code for my 1-2 shift solenoid, electrical problems in the lights and radio, and stick some new rear pads and rotors in the beast. Not too much more to go before it's 184% again
