Boas, comprei um leitor ODB2 e deu me 4 erros.

P0443
Evaporative Emission Control System Purge Control Valve Circuit Malfunction
The code indicates that there is improper purge flow in the EVAP system caused by a physically malfunctioning purge valve or, a shorted or open purge valve circuit.
Another symptom may be excessive pressure in the gas tank in the form of a "whooshing" sound when the cap is removed, indicating a purge valve that isn't working at all or stuck closed.

Esse som e pressao contece quando retiro o tampao de gasolina, mas nunca me cheira a gasolina em situacao alguma.

P0132
Sensor circuit high voltage (bank 1 sensor 1)
- Faulty Front Heated Oxygen Sensor Bank 1
- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks   

A cablagem da sonda lambda esta em condicoes há 1º vista.

P0171
System Too Lean Bank 1
- 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   
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.

Este deve ser a fuga de ar que ouco quando acelero e ele morre em aceleracao e subidas so em 1 e 2.
Tenho que mandar verificar o colector de admissao a ver se tem alguma rachadela.

P1132
Lack Of HO2S Switches sensor indicates rich (see P2196)

P2196
O2 Sensor Signal Stuck Rich Bank 1 Sensor 1
- Faulty Front Heated Oxygen Sensor Bank 1
- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Vacuums leaks   

Deixei os erros em ingles para nao haver erros de interpretação da minha parte.

Tirando o 1º erro, P0443, os restantes podem ser da fuga certo? Enquanto nao detectar essa fuga nao posso fazer mais nada.
Os tubos de vacuo sao novos e originais.
