I have 92,000 miles on my 2010 Mazda 3 2.5. I have been noticing issues with my rpm and idle. When i am in park or at a stoplight i notice my idle will go from .5 rpm to 1 and 1.5 and drop back down to .5 at idle.I noticed this after putting a brand new battery in. I have tried a a couple of things hoping they would help fix the problem I cleaned the MAF sensor also cleaned the throttle body. The problem is not as bad now but i still notice the needle moving slightly at idle and feel as if its not normal. Any other suggestions would help. Thanks
