I am reading a code 27 sub o2 sensor, they are original at 280,000.
I replaced the motor 2000 miles ago with one from Japan. Ran great, pre engine light,now a little sluggish .
I was thinking of just replacing both sensors before and after the converter.
Any thoughts? Brands? OEM seems to be 125 each not including gaskets from overstock. 54 each for bosch locally. We maybe selling the van .
Also the oil light blinked as the code engine light was blinking, maybe due to front being up on stands though.
thanks Donny
