Sounds like it is repeating everytime you run the engine at low vacuum,
opening a outside air door, and buggering up the water valve setting . Bet
your HVAC system has a vac leak somewhere.

Do these things have vacuum accumulaters?

Interesting. I've got an 03 Accord 4 cyl and the AC seems very good.
It was 90+ and humid over the fourth and we drove to a friend's house
about 250 miles away. We were very comfortable, the air coming out was
quite cold when the compressor cycled on.

I always assumed that there was a specific temp standard. I didn't
realize that it was relative standard, ie, 20 or 40 degrees below
ambient. I can't quite imagine why it would be that way. I would
assume the compressor cycles more frequently when it is cooler out,
but that it cycles at a specific condenser temperature regardless.
Apparently I'm wrong about that?

In repsonse to recirc mode, it happens wether this is on or not, just
most people say see if it still happens in recirc, which it does.

I have never heard of the cutout of the compressor and this would seem
to explain the what is occuring. I would say this occurs under medium
acceleration, during low acceleration I do not observe the problem.

As for short stops, say you come up to a stop sign, all clear stop for
1-2 seconds and go, then no problem. I have not felt the cutout per
say, but the engine is so whimpy hard to say if I could notice any
additional power.

One additional observation, when at the dealer I was unsatisfied with
their lack of interest in the problem, so I request to drive another
03 Civic LX and see if it occurs in the other vehicle. During the
drive we were able to reproduce the same issue my Civic was having,
just on a smaller scale. In the demo Civic the air did get warmer,
but not as warm as in my vehicle. That got them off the hook for now.

I guess this is just the case in newer Civic's A/C is not the best,
still better than nothing.

Have you checked that both radiator/condenser cooling fans run when A/C is
on? My guess is that the compressor just can't deliver enough liquified
refrigerant at low idling rpms and the receiver gets low on liquid during
the stop. IOW when you accelerate away, it takes a few secs to build up
enough liquid refrigerant to work efficiently again. I remember in the old
days, less stringent emissions standards, when A/C was on, the idle speed
would get a boost to 1K or 1200rpms or so.

Have you tried raising the engine speed, to say 1500rpm, when stopped to
see if that makes a difference? If you have an auto-trans that would mean
putting it in neutral of course - not very convenient but try a test just
to see what happens. Others have mentioned the compressor cut-out at high
throttle openings but are you actually accelerating that hard?

not an idleing a/c issue if you read the post, it's a performance
under acceleration issue.
it's perfectly normal on this car. the compressor cut's out when
acceleration rate is high. if they didn't have that feature then
people would be complaing that it had no power unde r heavy accel.

could also be a evaporator temperature sensor issue, could be a
control head,
putting it into self diagnostic mode and checking for DTC's would be
a good starting point. that feature does exist, i don't have a dtc
listing here at home though.
