idle RPM goes up and down (1000 to 2500 RPM) repeatedly in odyssey 2001 EX
2001 Honda Odyssey V6
I never had this issue before. After the cold start the RPM should come down and maintain there. But the RPM keeps going up and down as if it is getting pumped. I haven't tried anything so far since I don't know much about vehicles. Thank you.
sounds like either a low coolant issue or bad Idle Air Control valve. Is the the check engine light on?
