SOURCE: A4 1.8 02 plate - fault code p01297 - runnung poor

Code P1297(Connection turbocharger - throttle valve pressure hose) is related to air delivery to the engine. Unfortunately there is many components that could caused this code. For 1.8 engine the most common places to look for:
Check for damaged vacuum lines, next check over-bust valve(located in the intake hose) if holding vacuum, than I would check intake hose itself for damage or leaks. Some times broken throttle body can cause that fault (idle fluctuation). Lastly if car lack of power- damaged turbocharger can cause insufficient intake pressure.

Why is my 2004 gmc yukon 5.3 Z model Burning gas?


Was the fuel mileage better prior to replacing these parts? Did you use an aftermarket MAF sensor? Have you checked scan data parameters with a scan tool hooked to the vehicle for a test drive? I have experienced some aftermarket MAF sensors causing issues. as they are not calabrated properly for vehicle application. They will work, but with side affects such as yours. A road test with a scan tool hooked up and a technician that knows how to interpet the data should be able to give some insight as to what is causing the problem

Fault code p0171 what the problem


P0171 - System Too Lean Bank 1
Possible causes- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection Tech notes If the P0171 is combined with the P0174 code, it's very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replaced the air filter and clean the air flow meter. If the problem persist the front oxygen (O2) sensor may need to be replaced.

I have an '02 VW Cabrio that is giving me random 171 and occasional 102 OBD codes. I looked for and found a split hose near the air filter housing and replaced. I've not found any others with...


1st have you replaced the O2 sensor? Here is the technical stuff about this fault code
OBD 2 fault code P0171 VOLKSWAGEN - Fuel control System To lean engine cylinder bank number #1.
Possible causes:
Possible causes- Intake air leaks, spray propane around the intake manifold gasket and all vacuum connections and listen for a change in the engine idle speeds, any change indicates a leak.
- Faulty front heated oxygen sensor (a common cause if the car has over 50,000 miles on it)
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure Hook up a fuel gauge and make sure the fuel pressure is good/in specs under a load.
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

Can you post the fuel pressure spec for us? You have the spider fuel system? When you use a gage and check proper fuel pressure, with the key off will the pressure hold for a bit? If it drops like a rock, you have a fuel pressure leak.
Smell of the crankcase oil dipstick, does it smell like gas? If so, either you don't change your oil and filter very often or you have a fuel leak getting into your crankcase. If the problem is the latter, you fix the problem then change oil and filter as many times as necessary to get rid of the gas.
Check the fuel pressure regulator and vac line.

I have changed pcv valve twice and still getting oil in breather


The PCV valve does not control the oil situation, it just keeps the pans and valve covers from blowing off during a backfire. Excessive Oil in the breather is a result of excessive crankcase pressures, usually due to a worn engine, specifically rings.
SOME oil is normal, especially if you are loaded heavily and hard on the throttle.
There is a tester that measures crankcase pressures, but usually some other manifestation shows, like excessive oil consumption.

the PCV system draws crankcase fumes into the intake at idle and lower throttle situations. air going into the crankcase is filtered by the small PCV filter, where the oil shows up....

At highter throttle and lower intake manifold pressures, the system reverses, the PCV valve closes, and the fumes exit the crankcase VIA the breather filter. All of this is normal.

It costs tons less to periodically clean or replace the PCV filter.

Oil in air filter wot causes this car in qustion is a jag xj8


This issue is caused by crankcase pressure issue.
Normally filtered air enters the engine, runs through the crank case and then is pulled into the intake through the PCV valve. Durning hard acceleration, the PCV valve closes (to prevent explosion of fumes in crank case and blowing valve covers and pan off) and the PCV system reverses, with fumes coming back through the filtered intake.

Usually there is minimal oil that gets back into the air cleaner.

So, when somthing goes wrong, like excessive blow by, for example, the crankcase pressure overcomes the PCV valve and intake of fumes capability, and oily starts showing up in the air filter.

Investigate the crankcase pressure and PCV system.
