Fairtax4me Posted November 23, 2011 Share Posted November 23, 2011 So I hooked up a scanner to my wagon to check fuel trims today. Stft at idle and at 2500 rpm (sitting still) hovers around 0, but varies from about -1.5 to 1.5. Ltft at idle sits at a steady 4.6%. At 2500 rpm it jumps up to around 8.6 - 10.1%. Seems kinda high to me. Sound like the O2 sensor is fouled? Link to comment Share on other sites More sharing options...
