I bought a 2001 crv late last year. It was running fine for a couple of months but then it wouldn’t start at all. I replaced the timing belt and now it starts but it has a high revving idle. It’ll immediately jump up to 5000 rpm then drop to about 1000 repeatedly. I’ve checked for apparent vacuum leaks and found none. The throttle wasn’t moving when it was revving. I cleaned the throttle body which seems to be working fine. If you have any ideas on what the issue is your help is greatly appreciated.
