fiat g.punto 1.3 mjet performance

[michele30]

I have a problem with a grande punto 1.3 mjet, the car occasionally does not make and ? the saps say, but saw that ? a 90 hp should be pretty snappy.
This defect strange but not always and I'm still not able to figure out how to make them do more? often.
I've already done several tests and diagnosis, but I have not found parameters unpacked , but are the fault of the lambda probe code p0130 or p0170 I don't remember.
According to you, the probe can give these symptoms, not to make?
And' possible to exclude it from the map for not having more? this defect?

check the MAF may not read correctly, and then nn sends the right signals to the ecu

Hello diagnosis I checked the parameters in the bike and I have not found the particular variations with respect to the other car.
C'? a particular test I can do other than that already made?

[ugoboss]

check the EGR

[polini]

you need to check mass air flow sensor reading with the diagnosis see how much air law and compare it to another car if you can.
otherwise, clean the egr and mass air flow sensor.

[michele30]

the control mass air flow sensor and egr ? ok I had already looked at.
You say that the error of the probe can not give these symptoms does not make it good?
? can exclude if never from the map?

[Mikigor]

No the probe has nothing to do with. How to tell the colleagues exclude the egr and change the mass air flow sensor, maybe with an other car
To make a test.so you should solve

[michele30]

Thus, the error that comes out every so often to probe the let go..
I will try then with the mass air or egr

starts from the fuel filter and egr tap it physically and put an additive,has the fap-

Exclude from the map, the egr valve and flangiala, as someone has already suggested. The maf is not centered, or works or does not work. If it has the fuel filter clogged makes not always, not some you and some no, and the same if he had the dpf clogged.
