Hesitation?

so I noticed when I held the RPMs at 1500 if kept on dropping down to 1k then back up to 1500. I'm hearing a hissing noise that I never heard before possibly a vacuum leak. The X has also been sitting for a couple weeks so possibly bad gas? Possibly MAF?

Stick your head under the hood and have someone else on the gas. If it's a vac leak it should be pretty easy to locate.

Oh and on a side note.....Get your ass to X-FEST!!!

Check vaccuum hoses I bet one is cracked. If you can hear it it has to be pretty large.

Thanks guys found it. It was sucking air though a loose engine cover bolt.
