I thought you were talking about the washer having an effect on the sensor. If the pre cat sensor is gone I'd imagine you would have a fault code. Please just listen to Badger5 as he's probably your best hope of resolving this.ok but it could be the PRE cat sensor.? only think is im not getting a error code or a light or anything. would it be able to give me issues without a error?
If only you were so eager to help in my threadsand as I have already asked you for, logs of fueling...
can you get these?
its poke and hope/blind guesswork otherwise fella
