Hey you all my friend is having trouble in her 96 rav4. She has had the code for an EGR issue for years so I don't think that has anything to do with this new issue. Her car runs pretty good on the flats and in traffic. I just changed the plugs and wires and that helped the idle a little. The issue is this, going up hills the car just starts to slow. It will downshift but has a lot of trouble keeping speed. It just slows until you reach the top of the hill. I cleaned the PVC and a little of the Throttle body. Air filter is good and it has fresh oil. Maybe the torque converter is not doing something? Sometimes in the real cold something will kinda squeel when the car downshifts to make it up the hill. Any ideas?
