ok its my girls car 99 ex auto
ok i know that there is a power loss with a/c but it less power than usual
when i drive the car w/out a/c it drives fine but when a/c is on the gears go in hard and the car will jerk a lil on the freeway an sometimes when on a hill if started it will try to stall but wont this problem was worse but i changed
plugs
wires
rotor
cap
my ? is what could this be causing this no cel or anything

tune up. also the jerking could be a bad mount

i did a tune up as stated above rotor cap wires plugs why would it only jerk when a/c is on ? i doubt its mounts

my car is very similar in what's happening.....it's no jerking or anything, but the power loss seems like about 35 to 40 hp almost.......being realistic.....well, it's kinda annoying, and i'd like some ideas too.....maybe i need to get a proper drain and re pressurization..........

Start with the cheap stuff first.

try getting an a/c recharge. so that way it my flow better and the a/c compressor wont be as hard to turn so ur engine wont work as hard.

its normal it takes away like 15 HP and its an auto,

i understand there is power loss but lately its more than usual like i have to press the pedal more so it can drop gears

check ur filter, fuel filter ? lil thing to give u a lil more power?

Mine does the same thing.

It's a d16z6 and when I turn the AC on it loses a lot of horsepower. It puts quite a bit of load on the engine.

But I am not going to spend the money on finding the problem since I will probably rip AC out soon anyways.

It would be interesting to hear if there is an easy fix though since I'm sure it kills my gas milage.

So what I do when I have my A/C running is when i want to accelerate, I just hit the A/C switch to turn it off. Then when i'm just cruising I turn it right back on.... no power loss when i need it.
