Is my exhaust leak hurting anything?

That's the question. It has a leak in the exhaust manifold that you can clearly hear on acceleration. It's getting headers in a month or two, so no biggie???

Yes. Its screwing up the PCMs ability to easily maintain 14.7 A/F ratio. If the leak is bad enough, you will get a SES code. Just fix when you get the headers.

It will cause you to run rich and, if you have to worry about them, your emissions will go up. If the leak is bad enough, it can cause a misfire or power loss.
