Check your air idle control valve, check for the wires to be fretted or broke, and also check the vacuum lines to it. 
The air idle control valve mey be dirty and a good cleaning with throttle body clean through the throttle body may help clean the carbon build up. 
If there is a Auto Zone, have the Vitara scanned for a DTC code. 
Here is a few things you can do. 
Checking  the IAC (it's called the ISC on Single Point TBI)
It is screwed to the throttle body, and has a 2 pin electrical connector) with an Ohmmeter - the solenoid should be 11 to 14 ohm.  If not, replace.  


To test the IAC / ISC
Use a Duty Meter, and adjust the air adjust screw to get 50%.  If the revs are not right at that point, adjust some more to try to get them correct, but if the duty goes below 28%, a vacuum leak is highly likely.

Air Adjust screw for TBI / Single point   look on the Throttle Body, just below the fuel line and maybe an inch to the left of the Fuel Pressure Regulator - it looks like a cross head screw into the TB.

The 8v (Single Point / TBI) uses a throttle opener device to open the throttle extra during starting.  When the engine starts to run, a vacuum line is applied to the device through a vacuum servo valve, controlled by the ECM. The vacuum closes the throttle opener, to bring the revs down to normal.  The ECM will operate the VSV after about 10 sec from engine start (less if the coolant is warm).

Try these things for now and keep me posted. good luck.

MISFIRE, how did you prove rich, caused????????
if that is true, it can be caused by:
  1. spark plug bad. (no spark causes, wet tips)
  2. too high fuel pressure.
  3. PCM stuck in failsafe (limphome) mode, scan it yet?
  4. got DTC errors??? scan it?
  5. misfiring when? hot , cold engine or both.?
  6. only idling , cruising up hills? or all time?
  7. leaking injectors?
  8. clogged injectors.?
  9. ECT stuck cold all the time (scan it is it 180F or more?)
  10. and more. cant go closer lacking all EVIDENCE.

2001 ford focus se sedan revs to high after replacing icv and tps


It sounds like the TPS was installed improperly..It has to be set in place with no tension on the spring loaded mechanism...This will cause the throttle to rise...I don't know what problem you had before replacing these components but nothing should magically go bad while doing it unless it is a faulty new part...Try removing the TPS ..,INSPECT it to see the plastic lever operation is in correct timing with the lever it is mounted to ...Look close with a light to see what I am describing then carefully connect it....I've seen it happen before...If not the IAC..( idle air control sensor )..will cause it to have a high idle if it is bad....),,maybe it was accidently disconnected .....GOOD LUCK..

It stalls out at a dead stop or when turning.


When you say or when turning I assume this is because the revs drop down to the same idle speed the engine would do at a "Dead stop" if so this is probably a bad or sticky ICV (idle Control Valve) Did you notice any lumpy or high idle speeds in the lead up to this problem?

Rough idle, car has no ICV, idle control valve, so what now?


It will deffinitely have a form of idle control, sometimes it is part of the throttle body but there will be one... 100% certain.

Rough idle as in lumpy will not be an ICV related fault, as with ICV it will either have solid high revs or none at all.

It will either be an inlet vacuum issue - split hose, gasket, MAFS etc or an irratic voltage caused by things like a Lambda or worn throttle potentiometre

Describe the rough idle in more detail if you can, also are you UK or USA etc.

Do you know what cc and engine code your car is?
