I don't suggest K&N filters for any vehicle with a mass air flow sensor. The K&N filter is oil impregnated and can cause damage to sensors. Its better just to buy a ac delco replacement.

I am having similiar problems with my 06 Denali. Mine does the same thing but also does not blow hot air when in idle.

03 denalis do not have one, Gm discontinued them in 03,

Here's a link to a thorough article on the subject which should help you...

air and fuel filters, check fluid levels,

The fuel filter is contained in the fuel sender assembly inside the fuel tank. It is not serviceable.

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.
