Opel Corsa c

Hello good I have an Opel Corsa C 1.2 gasoline that if you accelerate normally only more than 2000 return arrives, however when it heats a little if you accelerate slowly, it lasted but if you do it suddenly nothing only arrives just over 2000 revolutions. I put diagnosis and sing oxygen sensor failure 2 after catalyst I looked at it and effectively would take something below that I start root cables, but I am doubting whether for this probe the car does not climb turns or can be the butterfly box. Alguen gives me some advice thanks

Hello everyone, Berny 00, the ECU Motor or engine control module, use the oxygen sensor 2 I would review the states of the fuel filter, measure the power pressure of the pump would be ideal, also fix whether the exhaust tube is strangled or folded by the blow or folded, if you have doubts, of the benchmark engines with electronic injection in the cold games, they do not take into account the signs sent by the oxygen sensors (Open Loop), then when the temperature), then when the temperature) With an exhaust soda ascends and with the help of the heater of the oxygen sensors, it enters Close Loop, regulating the richness of the mixture according to the residual oxygen in exhaust gases, therefore if the new starting engine fails, it is difficult to be due to problems in any of these oxygen sensors, if you have doubts disconnect the 1 ECU will work permanently in Open Loop mode, this is to definitively rule out a problem in that area.

Well Fiat 147 so I am in as soon as the vehicle comes again, it seems reasonable to me what you say since although my other doubt was if it could be the butterfly box that I have had to fail and go down and go around and come back and this is not the case, anyway you also have to put said sensor because I

Hello everyone, Berny 00, the butterfly box is possessible, but if it is electronic, without piola or accelerator cable, it is difficult to generate that problem without generating a code, if there is no mechanical connection between the accelerator pedal and the gase butterfly, it should be for security a highly monitored system by the ECU Motor, for safety, you imagine what would happen if it would happen if it would happen if the butterfly? That is, the accelerated engine thoroughly ... Dangerous not cress?, that's why I don't think the rpoblema fences there, the system in my opinion indicates that most likely it is that the fuel pressure this demolished decline, checks the filter, if it is obstructed or there is a problem in the pump can perfectly produce the problem you describe assuming that there are no other codes of breakdown. Check us, good luck and greetings!
