I have a 2001 Honda Civic LXi blew the headand i replaced it with a 2005 LX VTEC head engine. Im having problems with the idling it goes up and down between 1500 and 2000 RPMs I cannot make it stop I replace all sensors on the intek also reset the ECU I'm still having the same problem do I have to reprogram the ECU or get a new ECU? If anyone have any ideas or what should I do just reply

Do you have any large vacuum leaks? Leave the brake booster/pcv hose off? With a large vacuum leak it will surge the idle and have a high rpm idle.
