Obd reader wont work on an my99. Connect the diagnostic plugs under the steering column instead to read it

it will be the lambda sensor. Had the same on my MY00 sport. Under load check engine light came on. Went away after a while. Car will run rich until the sensor is replaced and will be hesitant if left for too long

an easy fix

It is the Lambda sensor just done the CEL thing and got error code 32 Oxygen Sensor or Circuit (No. 1, Right Side, On SVX). Is this the one closest to the turbo?
