when I'm cruising above 30 mph , if the a/c is turned on the car will feel like I'm pressing the gas pedal and letting it go, but I'm not doing that. I'm just holding in steady. If i turn the a/c of the car stop doing this. Any advice ?

 

its normal. when your a/c compressor engages it robs a little power (more drag) on your belt system. when the a/c disengages that lost power is no freed up resulting in less throttle to achieve same power. you never moved your foot off of gas so it feels like your accelerating.

a/c clutch is constantly engaging and disengaging during its duty cycle.

we are talking about a slight accel right?

 

yes slightly.. but it's cycling every 2 seconds ?? something is wrong.

 

bump

 

2 seconds is exagerating a bit.. more like every 7 seconds or so

 

no exaggeration.. every 2 seconds it feel likes i press the gas and let it go...
