do i have a vacuum leak?

On the 550 mile drive home with ny "new" 93L i noticed that whenever I'm accelerating the a/c tends to cut out. When I'm off the gas pedal it comes back strong.

Everything else seems normal, and it runs strong (at least as far as I can tell since this is my first lightning).

If by accelerating you mean flat foot WOT, then is okay. The ac is turned off at wot by the ecm.I would guess this is to reduce the load and give you full power.

No, not total WOT, sometimes just barely giving it any gas.

I think i found the problem, There's a very small tan hose near the winshield on the passenger side that's brittle and has a hole in it. Gonna see if that fixes it.
