Repeated P2098 Errors
Wondering if anyone has had an issue where repeated CEL for O2 comes back even after replacing and resetting the CEL.
I replaced both right and left bank since I read that Durametric has a mistake in it where the codes for Left and Right bank pre cat O2 are swapped. Still getting the error and rough running when cold.
I think it may be a bad connection somewhere as the sine wave for left bank is choppy. Right bank is smooth.
Any ideas?

Well u have a ground, 12v heater power, 12v in, signal wire out. If all the wires check out at the plug then u need to inspect the signal wire back to the dme as mice like to chew on them.
In my car i had to replace the pins at the dme due to intermitant signal and ground. A tech at some point had spred the teeth on all the pins.
Does the voltage in that o2 hang out at .47? Thats the default when the signal drops out.
