Failure P0091 Fiat Bravo 1.9 150 HP

[rego88]

they porter? the machine from a pompista

guys a question if in FES, I carry out the procedure where it says: replace the ecu and the injectors, what happens?
Why? today I tried but after the first step I cancelled...what might happen?

hello.... where are you? I solved a problem last week on a 159, had a map light, and as it sank zac... the problem was.... where are you?? he wants us to disassemble the pump dell high pressure.... and as for the corrections of the injectors at 90% resolve by adding the additive to the fuel injectors and with the reset of the parameters autoadattativi inside the engine control unit.....

[bravosport150]

I am pugliese and you?
I did not understand what this phrase means: he wants us to disassemble the pump dell high-pressure

[rego88]

the problem lies in the high-pressure pump.... must be disassembled and show it to a pompista bravo... you to solve the problem.... but to turn the pump to the tour you have to disassemble the machine, I'm in the marche.... a little lontanucci!!

You have irregularities at a minimum for the case? If you hot or cold?
Unfortunately I can not yet see the attachments...having the map I could give a hand... 2mm of correction are altini but there might be something to check in the map.
if you can send me the map in pvt I give him a look...I already had your same problem and I resolved, therefore, does not harm to try

thank you for your availability, but if you read the rules you know very well that we can send you the file in pm.

[bravosport150]

the guys here there are two schools of thought, those who say that it depends on the map and who says that ? the high pressure pump, now I'm trying a new map...let's see how it goes and I'll know.

rego88 but as time goes on to make this procedure and how many dindini serve approximately? THE problem ? the machine I need all the dd, that's why? I still can't decide to go to a pompista

*msport:
I'm sorry, but I didn't know not to ask for the file...I have not read the regulations clearly..
Thanks for the information anyway :-)

*bravosport150: if I were you before taking the car out of the pompista from which surely spend I would try to load the map ori, and verification that the anomaly is not present so? you can understand where is the problem... not try other map mod that does not make much sense in this case.
If the ori the car is fine you can rule out problems with the pump and look for the anomaly on the map.

[carmageddon]

if the car goes well with the original file, does not always mean that the problem was triggered by the modified file, or better, the modified file may induce error, but simply because? some body or the sensor are at the end of life.

[bravosport150]

it is in fact ori, don't you ? presented the error, but can? be that, in certain circumstances, and with the parameters the original the fault comes to the surface, but exit when c'? something that asks for more? of the original map, I do this last test, with this map, then change fuel filter and use the additive in the diesel and if still you have the error, I go right from the pompista, if I can find some gg ******...

[paolo159]

*carmageddon: you are right but you have to go for exclusion then in my opinion it from what is pi? simple, and then put the map ori, then to the pu? proceed with further testing..

*bravosport150: make a good analysis with the original map and do the data log you will see that if you actually c'? something wrong with the mechanics you see...once you make the log e-mail well graphics, as well as you did in the first post, looking perhaps to reproduce the same situation in which you had the problem.
Then a good cleaning of the filter, diesel certainly doesn't hurt ;-)
