SOURCE: idle irratic

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

you may need to replace the sensor or relay for the transmission. about the brakes, try checking the disc pads, it may be too thin, have it replaced

SOURCE: Revs too high

EGR Valve and pdfe sensor control idle speed. Go to the parts store and ask them to show you where the parts are. PDFE sensor is probably not working right. Any codes? And what do you mean your converters are empty? If the converters where gone it would give you lean or rich code.

If you have the electronic type odometer at the bottom of the speedo try this: switch the ignition to position 2 but not engine on (ignition on, engine off) hold for two seconds and switch off. Do this three times and check the odometer, it should flash up any stored error code(s), have paper and pencil at the ready. Codes will make diagnosis easier
