Posidrive Posted July 17, 2015 Posted July 17, 2015 If the CEL comes on does the performance get cut back to help prevent damage? Just changed a bad pre cat lamda sensor and performance was still sluggish until I cleared the error. Quote
DonCool Posted July 18, 2015 Posted July 18, 2015 The only time I have had an EWL with a performance drop has been due to a failed coil pack. It was intermittent for a couple of weeks then the car starting running like a bag of spanners permanently. Obviously, you need to get a fault reading to be sure. Quote

The P1031 fault code was the reason that I changed the sensor. Took a couple of days to get around to clearing the code from the ECU because the reset button on my code reader had broken. Quote
