I did unplug the battery. And strangely the light has been off for almost 4 days. (ive unplugged the battery to fix this b4, it nvr workd for more than a day) im just waiting for the light to come back on so i can switch O2 sensors and see if that truly fixes the prob. If not i really need the code deleted. & the funny thing is, now my car idles at 1300rpm (i havent done anything to the car recently) since the light went off. could the pcm be doing that? Or is my maf sensor bad, or could the below freezing temps here mess with the maf? anyone willing to scan my car for meto find out the issue?
