Unhappy A/C Troubles?

When I pull up to a stop sign or light with the a/c on, once in a while it will run horrible. Misses, shakes, and stumbles on take off. If you shut the air off and gun it a couple times it runs just fine. Only does it with air turned on, and only does it a couple times a summer. Any ideas?

Running the A/C puts a huge drain on the engine.

I'd most likely start looking at spark plugs and wires. You'd be supprised.

Sounds like the compressor is dragging.

Put new in new plugs and wires about a year ago. Could they be bad already? Wouldn't a dragging compressor have an effect on the motor going down the road?

it happens, AC clutches, when engaged, put a huge drain on the engine. new cars even have a WOT compressor disable function to give you full power when accelerating. It may be a bad bearing on the compressor clutch, or it may in fact be a bad compressor. hows your air filter? any other restrictions will be magnified by engine loads.
