unsteady rpm at idle
i leave my place 4 work, n' as i start my engin, the rpm starts goin' up till 2, then down till 0.2 then up n' down n' up n' down...
one more thing, it wouldnt start easily... i have to try 3 or 4 times. sometimes even more, but then i give it a 5 min break, n' it starts at a BLINK.
anyone knows why ?
yout throttle positon censor is going out change it and it will return back to regular idle
might be tps, might be a vacuum leak, might be the crank sensor losing signal. Guessing can get expensive. Why not take it to a professional to have it diagnosed properly. Then, if you feel up to it you can repair your car right the first time.
TPS sensor is doing its job since the vehicle is not stalling. Iif the TPS went out, it would not let the vehicle hold an idle at all!!!!!!! Idle/Air control valve is your problem. Very common problem. It's only symptom is that which you have explained.
had the same problem.. it was faulty sparkplug wires.. make sure there all gettin spark.
get your tpu looked at (throttle postion unit) thats the problem
You could try cleaning your butterfly in your TB and see if tha twill work.
Actually the car would idle, It would use a MAP or MAF sensor 2 compensate for it.
check ur ignition coil it may be faulty
your throttle position sensor is gone,and yes it will keep running.
