You kenot adjust, four throttle are not like normal single throttle, and this is quite normal for 20V Silvertop. Idling Valve dirty that's why and most probably vacuum passage blocked too - u need Throttle Body cleaning. I charge RM80 for the service. plz gimme a call if interestedae101svt said:my silvertop's idling drop to around 500rpm whenever the water temp reach half... wonder how to adjust???
Sometimes, Knock Sensor will cause Check Light to appear while driving. It could be TPS or Speed Sensor too. But to be sure when the Check Light appears again. Immediately stop and do a Diagnosis by connecting TE1 and E1 Terminals at the Diagnostic Box, put the switch to Ignition Mode (Don;t start the engine yet) and see if the Check Lights blink in uneven pattern - If no problem it will blink continously at 1 sec interval. If got some problem it will blink in specific pattern and to know what code just count how many time it blinks repeatedly before pausing. Once you have the code we will know what to check.ae101svt said:After cleaning the throttle body the idling problem solved - thanks EFN... but another problem occured… when I push my car to high speed with high RPM for a certain period the Engine Check Light will goes ON but the car’s performance still maintain very stable. Once I switched off the engine and restart engine again the Engine Check Light gone…wonder why this will happen…really need some inputs here. Tq.
