Hey,
About one out of every three times i start my car it runs like total crap for the first 2 minutes. It will sit there and cackle and backfire while idiling, and then if I drive it or rev it for a few minutes its back to normal. The car also seems to be running very rich under normal driving according to my air/fuel gauge, and doesnt bounce back and forth from lean to rich at idle and while driving as it used to, it occasionally will just be rich. Im wondering if this could be o2 sensor related?? An help is appreciated,
Thanks
Brandon

Are you getting a SES light?

 

Nope, I cant tell if its throwing any codes without the SES light though, because my scanmaster has been broken and at RamChargers supposedly being fixed for the past 2 months
