My 13 1.8L with 85,000 is rev'd once in park but mostly surges with low rpms. I have the dreaded P0171 code. Intake hose,filter is good. Cleaned the maf and 02 sensor. Spark plugs were changed at 45000ish miles. Any ideas?
Sounds like a vaccum leak coming from the fuel rail/ spark plug area. Almost inside of the valve cover. Any ideas? Is the pcv suppose to make a noise when shuttong off the car?
Is there any other codes? I had that code along with one other and it was changing the EVAP Purge Valve Canister that solved it. Also try adding some fuel system cleaner on your next gas fill.
