The vsc ,cel lights have been coming on when I have been driving for about half an hour then go out when the car cools down ,
I have had the car read and the code P1135 B1 S1 has come up ,After looking around the web I am now confused as to whether these means the maf or O2 sensor the car is going to a tuning specialist thursday but I would appreciate clarification before that so I am not ripped off for unnecessary parts
Car is an 2001rx I will be grateful for any help
