My car has suddenly developed a low, rough idle. It started happening after I dynoed the car. I was running a mix of 110 and regular gas. I refilled yesterday with 93 after almost completely emtying the tank and the idle is still bad. I replaced my plugs and the idle is still bad.
Does this sound like a bad O2 sensor. If so do I just need to replace the primary? Also where is the cheapest place to get an OEM O2 sensor?
Thanks
Josh
