Engine Mechanical problem
1999 Chevy Blazer 6 cyl Automatic
I sent the car to the mechanic and they fix a problem with gas regulator. Now, the engine service soon light is on and when they scan the code P0171 and P0174 shows up. They already check the oxygen sensor and its ok. Also they clean the inyections. Could you help?
