ever since i put my new filter in my idle speed when i first start it up drop below 1000, to like 7/800 rpms. it used to idle consistantly at 1000. i drove it the day i put the filter in and it drove the same if not better than it did before. is this good or bad?

 

idle is supposed to be 7-800, ur good to go

 

ok sweet, the new filter actually did something! thanks.
