Hesitation or bogging of my 1991 907i.e.

[nicoducati82]

I have had the same problem and, after cheking lots of sensors, filters, etc, etc...the mechanic found the problem...It is called: FUEL REGULATOR PRESSURE!!!! It can be fixed...don't need a new one. Part number 2834001 1A.

Éxitos!!

Hello,
I am new to this site and I am hoping somebody might have some advice. My 907i.e. paso best I can explain it, keeps bogging, hesitating especially when it heats up and I am doing a lot of stop and go. Also at freeway speeds I feel it cut out or hesitate, I am afraid it is going to completely cut out while I am on the freeway. Anybody have this problem or any suggestions on what to look for I would greatly appreciate it. Thanks.

Nico;
I agree - the fuel pressure must be regulated to 3 bar.
This is the EFI design operating pressure for the 907ie.
This was one of the first things I suggested to check (see earlier posts)...
