Yesterday I removed ISV (N71). It was working when hooked to 12v. Its like a 
flap valve, I cleaned it with WD40 and rubbed the surface with soft cloth and it 
was shinning. To remove TPS i ll try with phillips bit. I think i can chk TPS 
while still mounted by MM using small alligator wire and moving the lever on 
left side below ISV. It ll show change in resistance on MM or Should i remove 
the TPS and chk?

....  And the reason that you need the TPS, is for proper (any) function of the 
Idle Stabilizer (N71).  It kicks in based on rpm (~1000) and the (closed) signal 
from the idle switch.  If you are missing the idle switch signal, the ecu 
doesn't know to activate the Idle Stabilizer Valve.

That is a symptom of a bad TPS Idle switch. You can ck the TPS with a 
multimeter, on the PT engine, the plug should have a BN/BK (Ground), G/V (Idle 
Signal) and BK/W (WOT Signal).  The Green Violet goes to pin 52 on the ECU (idle 
switch).  Remove the plug, ck for continuity on the TPS to the pins that connect 
to Brown/Black and Green Violet.  You should be at 3ohms or less.  If 6 or more, 
replace TPS.  If ok, ck continuity to pin 52 at the ECU and Green Violet on the 
Plug.

Thanks for ur help. I ll try to tell the exact story. While driving in 
  
  
  residential area, I slowed down at a bend when first time the car stalled and 
  
  
  when i reached home and engine was idling it stalled and stopped. Now I crank 
  
  
  the engine it starts after very long ignition but when i remove my foot from 
gas 

  
  
  
  
  
  pedal it stops immediately.
