My car is having some problems kinda similar to the lower thread about asthma. When acclerating its cutting out/hesitating aswell as going up hill and stuff. I ran my lil code reader on it and it says. Emissions (lambda) Control. I was told before thats the O2 sensor but there a seperate sensor for O2 sensor. One is for just O2 Sensor and the other is o2 sensor heating relay. Can anyone shed some light?
