05 Sportivo "coughs'

[narnie]

Hi all

First time user and stumbled across the club searching for some answers on the net. I have a 05 Sportivo 2.4l manual that ever since new "coughs"/"chugs", when the a/c cuts in and out. My dealer has said there is nothing wrong with my car when they put it on their "computer" but in 2-3 gear there is a noticeable difference. I would appreciate any input as to what you think may be causing it and any possible remedies.

Many thanks.

The A/C will make a click type noise when it cuts in and out... Thats normal as the compressor clutch is engaging...

Thanks Ben but it is the actual engine losing power as the compressor kicks in and out giving the feeling of it coughing. I run 95/98 fuel and have installed a K & N air filter thinking this may improve it but still the same, although now it is at a higher rev when it "coughs". I am only assuming it is the a/c as that is what the dealership is identifying it as being, however it does seem strange that it does this at almost the same spot im my street everyday!! You wouldn't think the a/c was that routine!!! Thanks again for your input.

The AC will take up a lot of power from a 4 cylinder...

You'll notice the car struggle up hills and so on...

It's just the way it is...

There is the problem right there, some things the computer can't tell them. Ask them for a time when they can test drive the vehicle with you present or even with you driving and show them what is happening. The problem probably wont show itself when called upon
