Subaru legacy problem

prt21, Apr 5, 6:34pm
Have a legacy b4 2001 twin turbo manual. Cuts out at 100km when going up hill, and stutters abit when going up hill - seems to drive fine on the flat though. Have tried replacing the AFM and no luck. Anything else I should look at! Thanks in advance

what you have described sounds like fuel starvation .

using 95 fuel, sometimes shell.

You really should give it a diagnostic test first, As a guess #3 could be right, have you had this problem with a full tank of fuel! The problem with replacing the fuel pumps on the be/bh models is that Replacement walbro fuel pumps and others hit the bottom of the tank and neither a gss341 or 342 is the right replacement, should be looking for a 340 but don't bother you can't get them. You can run a 341 or 342 but not even the small 90'' bag clears it and either pump will only fit without the bag which leads to fuel starvation.
