Cool Fluctuating RPM while on the gas
Hey guys
I have a slight problem, my RPM is going up and down maybe 100 up and down while I am on the gas. Does that mean I have a vacuum leak?
I changed my air filter and exhaust recently, is there anyway to check?
Thank you!

You should take the air filter back out and make sure it is properly seated in the air box and that the air box is properly seated

It should sit flush, filter, and air box should all be seated properly

No, if you have your old filters, slave them in real quick and see what happens
