Hello all, hopefully I can get some ideas as to what is going on with my
car before I take it to the mechanic. My car just started giving me
problems, when I turn the ac on, it seems to really strain the engine, it
feels like it doesnt have the same power. When I am coming to a stop, and
going very slow, it will stall. It starts right back up, but dont know what
its problem is. It does not do this when I do not have the ac on. Any
ideas?
Thanks for any help or info.

pcv valve i bet. had the same problem when i got my car. they at least
"said" they replaced the pcv valve, and it went away. mine never stalled,
although it wanted to. good luck

My Acura's been like that since the day I bought it. Never stalled, but
with the AC on my gas mileage goes down dramatically, my horsepower goes
down dramatically, and even the idle drops. Whenever I asked anyone about
it they said that the AC takes a lot of power and it was completly normal.
Maybe I'll try changing the valve, they're not too expensive so it's worth
a shot.

Running the AC compressor takes an enormous amount of power. I doubt the
PCV valve would only cause a problem when the AC is on, and I would imagine
there should be some kind of check engine light if it did.:2cents:

not nessesarily. my lite didnt come on. when i had 4 burnt plugs, my light
wasnt on. tho there was a code. the engine was misfiring on several
cylinders. but no lite. and the lite does work properly

The symptoms are perfectly normal. In my MSM, the idle at a stop is 800, if
you are coasting in neutral its 900. If you are standing still at 800rpm
and turn the ac compressor on, idle goes to 1000, I guess to compensate for
stalling due to loss in power.

It's not the idle that concerns me. It idles fine, and like you said it
rises with the AC on.
It's the lack of power on the takeoff. The way the RPMS drop a lot faster
between shifts, and most of all the gas mileage.
Although there isn't much to be done about the MPG, no car I've had or
driven is affected by the AC as much as this one. Then again it's also the
smallest engine I've ever owned . . . in a car.
Oh, and my check engine light definately works. When misfiring or poor O2
readings. Throughout the life of the car I think the lights been on more
than off. I've got a friend with a scanner and I've never seen any PCV
codes.
I have to admit I feel a little wrong posting about my acura in the
domestic cars section.
