Reset your injector timing to compensate for the added boost at idle
I have 200,+ miles on the car. I change the plugs and wires yet it runs rough at idle and runs smooth at crusing speed. What can i do?
With any turbo it is a good idea to let the engine idle briefly before turning it off. This allows the turbo to slow down before losing lubricant. If you don't let it idle it probably won't hurt anything, but over time it may cause the turbo to wear out faster.

The TURBINE inside a turbo-charger stops spinning when the vehicle is at idle because there isn't enought exhaust pressure to keep it spinning, lowering the internal engine pressure. creating less wear on the turbo and engine also alowing the engine to idle.. if it was to continue forcing air into the engine it would also need to force gas. to match the air fuel ratio to keep the car from dying, causing the engine to rev.. not stay at idle..
Some turbo cars will be fitted with a turbo timer, which keeps the engine running for a specified time after the ignition is turned off. This allows the turbo to cool down before the engine shuts off, which prevents potential damage to the turbo.
To adjust the idle on a Suzuki Quad Runner 250, locate the idle adjustment screw, typically found on the carburetor. Start the engine and let it warm up, then turn the screw clockwise to increase the idle speed or counterclockwise to decrease it. Aim for a smooth, stable idle around 1,200 to 1,500 RPM. Always make small adjustments and test the idle after each change to ensure optimal performance.

If a Carina Turbo will turn over but will not idle there can be an air leak. The vacuum lines should be checked to see if there are any holes.
idle air control valve needs work. either clean it inside and out or replace it. could also be the maf sensor
turn the idle screw on the throttle body
Idle speed is computer controlled and is not adjustable.
