To adjust the idle speed on a 1989 Isuzu Rodeo, locate the idle speed adjustment screw on the throttle body. Start the engine and let it warm up to operating temperature. Then, turn the adjustment screw clockwise to increase the idle speed or counterclockwise to decrease it, checking the RPM with a tachometer until you reach the desired idle speed, typically around 800-900 RPM. Always ensure that any adjustments comply with manufacturer specifications for optimal engine performance.

If your engine is ideling fast its probably temperature senser. There is no adjustment for idle. that last answer is not entirely true. u can adjust the idle. but it depends on if its a throttle body unit that looks like a carburetor or a smaller unit. on a TBI unit, there is a screw u can adjust but the only way to adjust it is with the right tool. its not a Philips screw or straight blade. but if its idling high or fast it might be the idle air control valve. the one went out on my 1985 sunbird and caused it to idle funny.

Carburetor chev 454 89 throttle body carb idol to high how to adjust?
'89 Chevy used Throttle Body Injection, which is computer controlled. The throttle body is electronically controlled, and the idle is controlled by the computer. Check the IAC (idle air control) solenoid, and make sure it is working. It is a large cylindrical solenoid that screws into the throttle body, and should have a four wire connector on it. Also, the computer is programmed to raise the idle slightly if the A/C is on to keep the alternator charging, so be sure to check that.
How do you adjust high idle on carburetor 1988 trx200sx ATV?
According to my service manual for a 1987 (same for 86 through 89)these carburetors have a fixed high speed jet. The idle is adjusted by one screw on the right side of the carb which sets the slide opening. Another adjustment is the air adjustment on the left side of the carb. The air must be set first by turning it in until the engine is about to die. Then back it out till the engine starts to run rough. Turn the screw back in to exactly the mid point between these two limits. Then adjust the right screw to the idle speed. Both screws are accessible from the outside of the plastic side cover through the slots. It may take some looking and moving of some wiring to see them but they are there and accessible. Good luck.
