A quick question about lambda, I have a 85 190E 2.3 8vlv and I got a multimeter with duty cycle also, but when I hook it up to pin 3 in the diagnostic port, the reading does not change then when it is when the multimeter is not hooked up to anything al all, am I doing something wrong? Checking voltage shows a stable reading, not fluctuating as it's supposed to be, O2 was just changed and reports correct readings to the computer, what am I doing wrong? Does my car even have fault codes?
