well i just got gas, and after about one minute of driving my ses indicator came on. i've heard that if your gas cap isn't on properly, your ses light will come on. i ran the code, it was P0136 (o2 sensor circuit malfunction).

my question is if this code would have anything to do with that. is there anything that would cause this specific problem, or is it simply a bad circuit?

thanks in advance

 

I've had that, which developed into a O2 sensor issue, which grew into a system too rich, I still haven't made it to the dealer but I think their response will be interesting. Its at least another two weeks before I'm there and this is a very intermittent problem but I'll let you know.
