peugeot 207 misfire

I have owned the peuugeot 207 1.4 h for 5 months, it has not been a problem for the last 15 days, but for 15 days, when the engine reaches 70 degrees when it is cold, it rises up to 3-4 thousand revolutions, as if the fuel runs out in such gasoline or gas cars, after 70 degrees, on the straight road as much as I want. or I do not force me on the ramp, I took it to the master, connected it to the computer, no problem appeared, dismantled the injectors and checked it. a tool master of such problem?

I had a similar problem. i have peugeot 206 1.4 hdi. At first it seemed like the vehicle was cutting gas instantly. Later on, he started kicking as he climbed uphill. he had begun to do it on the flat road. even when the engine is quite warm. Then I showed it to the master and connected it to the computer. the computer did not see. “I guess it's bad,” he said. We toured by car. the master said from the injector. we made the injector now my vehicle is in good condition. moreover, there was no problem with the client. the computer has not seen. frankly, I don't know much about the engine, but I hope this experience will help you.
