This is the only problem I have.

It did not do this a couple days ago when it was 45*F. However today it reared its head again, it's 7*F.

=I know it is a fuel cut, my a/f goes off the chart lean, so I suspected the fuel system (as per zilvia recommendations last winter - fpr, pump, filter) but it never had any trouble with cold/hot starts.
=Has only happened on the freeway.
=Only when it is cold (at or below freezing).
=Happens in 3rd 4th and 5th.
=TP doesn't matter.
=I can cruise at 95kmph all day

SR20DET redtop,
Apexi neo,
Japanese gauge cluster

I would think this is just the SR speed limiter, except 100kmph seems low

thanks for the help
Michael
