Engine Mechanical problem
2000 GMC Jimmy 4 cyl Four Wheel Drive Automatic 96000 miles
My engine light comes on and then goes of with in hours or maybe the next day. I ran a dignostic test and it came back with the codes of p0101 p0174 p0171. What does that mean and I just had the fuel pump replaced last week. I have put so much money into this SUV than any other car I have owned. Its Killing me.
