Just following up with where I am with all of these codes.
After extensive searching for a upper air leak to no avail I came back to the forums and was doing more research. I read a post where someone said to disconnect my mass air flow sensor and see what happens. As soon as I removed the MAF connector the car immediately ran better and was no longer stumbling at idle. I cleared the codes and drove it for sometime and all seems well. No more P0174 and P0171 codes. After a restart I did get MAF related codes from it being unplugged. Im guessing that my 2 year old (BOSCH) MAF is failing. Ive already tried to clean it with no results. Ill have to buy a new one I guess or try and see how to test the current one.
In the mean time will I be OK to drive the car with the MAF disconnected? Will I do permanent damage? Seems to be running better than it has in a long time.
