Boa tarde! Isso que você descreveu no seu Nissan Dualis 2.0 2008 (também conhecido como Nissan Qashqai em alguns mercados) parece estar relacionado a um modo de segurança (modo de emergência) que o carro entra quando detecta uma falha, especialmente no sistema eletrônico do acelerador.
Se o motor funciona normal ao ligar, mas para de acelerar durante a marcha e só volta a funcionar ao desligar e ligar de novo, pode ser:
- Problema no corpo de borboleta eletrônico (sujo ou com defeito)
- Sensor de posição do pedal do acelerador (APP sensor) com falha intermitente
- Sensor de posição do corpo de borboleta (TPS)
- Chicote ou conectores soltos ou oxidados
- Falha no módulo de controle (ECM)
Recomendo escanear o carro com um scanner que leia falhas no sistema do acelerador e veja se aparece algum código relacionado além do B2099. Verifique também o estado da bateria e do sistema de aterramento, pois tensão instável pode causar esse tipo de comportamento eletrônico.
