SOURCE: 2000 Nissan Sentra rough idle
a rough idle/high idle is indicative of a malfunctioning TPS(throttle position sensor) this is located on the throttle body ,is attached with (2) screws/bolts to the throttle body housing right off the butterfly shaft. it has either 2 wire or 4 wire plug. the replacement part can be purchased at locale auto parts store. I would also agree that a full service and tuneup be done. this will help with performance and will increase the fuel efficiency. please rate this...thanks

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.

You may have dirty or clogged fuel injectors, may also be problems with the ignition system. Might also check the fuel pressure to make sure the fuel pump is working correctly.

sounds like a vacuum intake leak..check a those little tubes for cracks and security. also check your transmission levels, this will sometimes cause a surging problem while driving..if all this checks good then it might be dirty or clogged injectors..purchase a can of Sea Foam from Autozone $10 pour in 1/2 can to half tank of gas and drive around for thirty minutes..highway driving preferred, and see if that will clean up the fuel system.Can i get some feedback, thanks
