Alfa 147 error P0091

[walter_ie]

I told you that it was a problem of the map....modestly, 147 I know a memory, and cn my dp, the change of turbine sn managed to get to 250cv... anyway, it works on the time d, injection and lim IQ and you'll see that it shoots out of power... on the rail in the map stay low... then let me know bullet goes...

Walter is not the map problem, because if I lift the rail also 0.1 va in the recovery. The same map on the same car goes quiet.. I don't know if the other car has the pump overhauled but at this point I presume of you.
So the problem now is that I have the mapping on all the maps except the rail.
What does it imply to keep the rail ori?
What are the limitations of the provision that implies?

Hi, test with a diagnosis to measure the rail as much as you have pressure only to the framework put and write it down here

Thanks friend, I provide in the week to do so as they are out of the house and work the hours of abnormal (shifts h24)
Thanks 1k, and I hope to resolve the problem in a way lowcost!

Grazià you swear that the ioc tried with delphi to make a real-time, which he calls flyqualcosa but formats in RAW to the microsd and I didn't understand how you extrapolate the data.
The ioc put na day to understand that I had to press the button on the device to register. floor plan I do I'm the caper of the log!!! :°D
I hope de fixes co is in the machine, otherwise the exchange and waffles.... me costs less to change it that spending money for parts..

had a problem on bravo same problem changed the pump rail and the car, and come back to life ..but before changing pomap the pompista I changed the spout back thinking that was the spout that acts as a pressure valve mechanics, but nada ...in the end it was the pump itself!!

it is a known problem on the 147, they are the pumps of high pressure, it is useless to change it and put it in used, you have to review from a good one and solve the problem.

I'm having the same problem on the Bravo 1.9 120 bhp. It has been proven the pressure low and it looks ok (4.5 bar). Sensor rail changed recently. It was clean the the entrance to the pump where there should be a filter and the situation has improved a lot, but it's still in recovery (before it was almost immediately). Now let's try with the pressure regulator, but I think it's just the pump (the car with 70000 miles! absurd!)

Thanks for the confirmation Ugo, Saturday I removed all the pipe from the tank to the injectors and in fact I have not found anything that could block the flow of fuel.
Can you tell me approximately the cost of a review of the pump hp to increase the range how much is it?
