viclykewhoa Posted February 28, 2006 Share Posted February 28, 2006 My 1999 GS300's CEL comes on and off. Recently it has stayed off longer than usual after I put SeaFoam into the gas tank but it still comes on after a while. I have also pulled an OBDII code: P0125. Can an O2 sensor cause the CEL light to come on and off? If it's an O2 sensor shouldn't the light just stay on??? Also, when the CEL is on, my car idles low and power delivery isn't very smooth. The car jerks forward from a stop a bit. Sometimes, when I step on the gas, the engine revs go up but the car doesn't accelerate normally. It's as if the clutch is slipping... lots of engine revving noise but no movement. Has anybody experienced this with their GS300? Quote Link to comment Share on other sites More sharing options...
