Hey. I have a problem. Namely, in my Astra, the error P0170 appears and disappears. I've read that it's a poor mix. A familiar mechanic said that the first lambda to exchange because it reacts badly. After its replacement, nothing has changed. After buying the car I was searching a bit from what it could be. And so I checked the value from the flow meter is about 2.7g / s on idle, so it's OK. Lambdy, when they get hot, oscillate first the more violently the other calmer. At some point, I gave up the error and I noticed that he was leaving. The engine works nicely, evenly and accelerates well. I recently added a gas installation, but this has not affected this problem. Where to look for causes? Maybe the electrician does not touch somewhere?
By browsing other forums / posts regarding the same error of other users. They gave this value (or its reckoner per kg / h - I do not want to specifically look for it now), writing that it is in TIS for idling.
Finally, I bought a meaningful interface and a few flowers came out. Namely, besides P0170, inactive P0100 (flowmeter signal too low) and P0460 (Fuel level, signal too high) were still hung. Any suggestions? In the free moment, I think I will take off the connection between the collector flow and see if there are any cracks.
P0100 may suggest a flowmeter failure which is quite common but may also indicate a failure of the motor controller. This time, it helps to provide a separate mass on the flow meter. But it is suggested to first install another meter and observe the OBD corrections.
I have astra x18xe with LPG, error P0170 appeared. The car runs standardizing. There were only problems on the cold engine that it lacked power. After 2-3 minutes everything was back to normal. The car was at the mechanic's, apparently, he checked everything from the lambda to the fuel pressure injectors, the flow meter was replaced because the old one reportedly showed too low flow. And he claims that only mechanically, for example, valves can be burnt out. And I want over 3,000 for the repair. I don't want to believe it.
