Sudden high idle when started that doesn't come down (1800-2000 rpms) also accelerates slowly


Check for any disconnected hoses that may be causing a vacuum leak resulting in a high idle. Make sure coolant level in radiator is not low which can also attribute to a high idle.

Idles too high

Vehicle shuts off sometimes when stopping


Set your idle speed to mfg recomindation if that doesnt help check the dash pot that is what keeps the engine from stalling at sudden speed reduction

Low idle


Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk 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.
