2000 Sportage 4x4 2dr. convertible. Manual transmission. 137,000 miles.
If you are stopped, and the air conditioner is switched on, the car will not accelerate, at all, it bogs down completely and the engine nearly dies. You push the pedal to the floor, and nothing happens. Very dangerous! However, if you switch the A/C off, it accelerates normally, as if nothing is wrong! When you get up to 30 MPH or so, and THEN turn the A/C on, everything runs normally, no adverse hesitation, and the A/C works well and is nice and cool. But, once you come to a stop, the car will NOT go again until you turn the A/C off!
Anyone have any ideas??? Thanks.
