Idle Air Controller
Two days ago my engine RACED to 5000 RPM ++ upon initial start up. This happened twice and it was suggested that I clean/check the Idle Air Controller.
So, yesterday I took the Idle Air Controller off my engine and cleaned the valve with some WD40. It seems to be moving freely. I reinstalled it and all is well.
How often should I check this thing?
Should I just replace it?
Is cleaning it a good idea?
Thanks!
