Hey guys,
After starting up my dsm, it idles pretty high and eventually comes down after about 10 minutes of driving. However, after this amount of time at a stop/idle, it begins to choke and go down to about 300rpms, almost die, and then come back up again. It will repeat this process until it eventually turns off. Also, when I am driving, if I go in to neutral, sometimes the rpm's will fall down all the way and the car will completely shut off.
I originally thought it was a vacuum leak (it may still be although I have checked most hoses), loose clamps, or even bad gaskets. I recently checked for codes and I found that the o2 sensor is bad. Could this be the reason for my bad idle and extremely rich condition. I am blowing lots of black smoke out of my exhaust upon hard acceleration. Thanks
