tommyjack Posted March 18, 2004 Report Share Posted March 18, 2004 92 STS, 4.9 engine. Car has a miss after driving for about 30 minutes at hwy speeds. Miss comes and goes but seems to occur more when the outside temp is warmer. No engine codes. News plugs/wires/coil within the past 4000 miles. Could it be a O2 sensor or TPS? Any help would be greatly appreciated. Link to comment Share on other sites More sharing options...
