ok the last 2 are o2 sensors... those will just have to be replaced.. you can rent the special tool at autozone;... speed sensor malfunction.. i'd say replace the speed sensor and go from there.. i'd start there the other 2 codes sound like they're related ot the others... also, check thoroughly under the hood to make sure you dont have any burnt wires.. did all this happen at once? or jus tover time? the front o2 sensor will make your cr run like *** so fix that one first...
