Emissions question
Had my wife's '91 Spider inspected yesterday and the HC reading at low
idle seemed pretty high. The car passed but the reading was 171 for a
220 ppm standard. I changed the oil, plugs and air filter right before
taking it down there. Any ideas as to why the HC reading would be
high ? Perhaps its time for a new O2 sensor or perhaps the temperature
sensor is causing the engine to run too rich at idle ?
