Lambda probe fault possibly

Blocked or defective cat or the exhaust sender unit is faulty

go to an accredited service center that has experience on your make of car as the guessing is costing you money
the first thing that a professional shop would do is run the fault codes and then decide which codes were attributed to the problem
removing the fuses may cause more problems because you have no idea what the problem is and will never have any idea until the codes are read

first make sure you have no close in silence ( catalatic ) exhaust line ) , second make sure the Oxgen sensor is connect (lambda) ,and the timing is ok. intake manufold sensor remove and clean , for catalatic you can loose bolts only to check and accelerate.good luck.

from the exhaust manifold you have a pipe going down to the first box(cat converter),the lambda probe(o2 sensor) is between these two.looks like a tube sticking out the side.

poss a cat gone or lambda probe,the probe is cheap to replace the cat aint.......

How many miles or kilometers?

sounds like a faulty air mass metre or lambda sensor throtle position sensor depending on which year or model id get its fault code read

clogged catalytic converter

Hello, VW polos 1.0, 1.4. 1.6, suffer from carbon bulid up in the throttle bodys causing bad idling, esp the Bosch Mono-Motronic (Throttle Body Injection systems), a good clean with carb cleaner should repair the problem, also engine temp sensor replacement and idle speed control valve replacement can help idle problems.

Dear Customer,

1
check your sensors 1st,all sensors must be good

2
if all sensors are working good than check your engine firing sequence,some times happens when sequence was wrong,

3
check your exhaust and carborator tuning pin that creates the batter combination for firing in bore for batter performance & less emitions ,so check is it ok or not than go to your nearest service center that havad certified mechanics,

till you read this you had solve this problem definatly,
