as the title states, my D15 idles very eratically. im not sure the problem, but i do know its a common problem in many hondas and mazdas. as soon as i turn the car on it starts the idle at about 1200-1500 and revs to 2000-2500 for about 30 seconds or until the car warms up.

any advice would be fantastic. Thanks in advance.

 

Let me know. I will look at it.
