p0171 gone now p0172???????
00' cavalier 5 speed 2.2 had a p0171(system too lean) figured it was the map sensor replaced that didn't work found out it was the wires going to it, replaced them got rid of the p0171 now I have a p0172(system too rich) seems to be a never ending battle. anyone else have this problem???
