Hi All!

Having fun with my new (well, new to me, anyway) Forry the other day,
I found what feels like a fuel cutoff happening when I attempt to
accelerate thru 110MPH. Backed off and tried it again, same thing, and
right at 110. Definitely not a rev-limiter issue, as the motor was
spinning at something less than 5000RPM at the time. I will comment
that the SOHC 2.5 was pulling strong between 100 and 110, and would
undoubtedly have made 120 or 125 before running out of juice. This on
an empty stretch of highway north of my home, at an elevation of
around 7000ft.

Not that I make a regular practice of going that fast, mind you, but I
really resent Subaru deciding _for_ me that I'm having too much fun

:-P

Anyone know anything about this? Any easy way to disable it? TIA!

ByeBye! S.

Your probably just running out of pull. My WRX stops pulling at 120 then it
just creeps upward.

I have a 99 forester too and there is a limiter at 110 mph. ITS
LIMITER not the limit of the car. The car could easily go past tha
but as soon as u hit it ur rpms go from 5000 to under 1000 and the ca
jurks back as if u let go of the gas completely. I have looked for
way to remove it but i have found no such mo

Glad someone else has experienced this. I thought there was some
possibility that there was a fuel pump issue as someone suggested, but
a long full throttle pull up a steep stretch of mountain highway the
other day failed to invoke the hiccup I experienced at 110MPH. Note
that it was _exactly_ at 110, too; not 108, not 112. Hmmmm.
Anyway, my wife has an '02 Forester. I'll sneak it out early some
morning and see if it has the same issue.

ByeBye! S.
