Question about 2000 Honda Civic
After warming up for a few minutes at a nice steady idle, the idle speed surges up and down. It seems as if it wants to drop down to a warm idle speed, but then jumps up, and continues the cycle. Fault code P0505.
Is it the IACV?
Check your high idle valve may need to be replaced.situated at the side of throttle body.

It sounds like a temp switch problem.
