Question about 2004 Chevrolet Tahoe
I have a 2004 Chevy Tahoe. The vehicle starts perfectly fine and Idles normal. The vehicle continues to perform normally as I drive and move up through the gears. However, once I've achieve my desired driving speed which I intend to maintain, whether its 30, 45, 55, 70mph, the vehicle starts this stuttering/sputtering until I let off the gas. Which stops the "rumbling" until I start to press to gas pedal again 30 ft or 500 ft (intermittently) down the road, it will do it again. I just put in new spark plugs and wires. Still malfunctioning. Checked MAF. That was all good. The tires have been rotated, balanced and front-end assemblies inspected for warping, and "play" outside manufacturers specs. All still good here.
Sounds like you have a fuel pump going bad or a clogged fuel filter. Change your fuel filter first.

you need to find the fuel pressure release around the fuel rail press the little tab when the car dies. If there is no fuel coming out from that point, your fuel pump is going.

Some things you can check. First, with the engine off, look down into the carburetor and quickly move the throttle. You should see a squirt of fuel. If not, the accelerator pump is bad. If that is OK, check the spark itself. It should bridge a half inch gap with no problem and should be healthy (have good "snap" and bluish color). If OK, check the two wires that run from the ignition module inside the distributor, down under the breaker plate.Often those wires can partially break or short to the housing...when the advance moves the plate it will cause a problem.
Only other thing I can think of is timing. That engine likes from 8 to 12 degrees advance (depends on fuel quality) if it's set wrong it can make it fall on it's face when you floor it. (bad chain can do that too).

Check your coil it should be on top of your distributer cap, remove 4 small 1/4 in head screws and expose the coil 4 more screws hold the coil to the cap remove coil and take to autozone or vip and have them test it for you..
