ISC valve

[ajnone]

hi sifu-sifu,
Can we clean the ISC valve for BT, SVT or GZE by DIY? I guess i am not the oni one who appreciates for the help. Idle problem might be the common issue for our Toyota members who driving these engines…… Any sifu out there come across this DIY, maybe can help us to save some pocket $$$...
Thanks for advance :rolleyes:

since taking out ISC valve is so much work, mind as well take out the 4 throttles to clean one shot.

labour RM50 max

screw driver!
