I know this is very vague but my wifes 00 yukon acts like clogged fuel filter. Its not real bad but you can tell somethings wrong.Just changed rear brakes along with new rotors i can see they are not sticking. Of course fuel filter, clean air filter new plugs. I use good gas always and mobil 1 oil.Past summer i did hear some popping in rearend from limtd slip.After the additive it stopped but im wondering if there could b something more in there.I really dont know what to try and there are no engine codes.Any ideas i will try them please...DAVE

On the engine running always check for good fuel pressure and basic tune up.
How many miles since last tune up?

On the rear end check the oil level and pull rear inspection plate off and have a look at limitive slip stuff.
Sometimes limit positive greese and additive helps.

on the limited slip replace differental oil every 30,000mi more often if towing...... always use 1 bottle of additive this type of differental creates more debris as componets wear......

if you have over 100,000mi and fuel gauge is inop aren't they all ! I'd get oem as other pumps fail early.......another componet is the O2 sensor as these at 100,000mi are in need of replacement this should keep cat's and fuel mileage in good shape........make sure fuel pump ground at fuel tank area is not rusted and make sure its good connection to ground.......

You are welcome.

I would rather go Old Mexico than China or other way off stuff.
90 day wonder if it is going to run stuff.

Ac Delco/Delphi is the only best and safe way to go.
I think Delphi is still US made or was the last time I looked.
Good Luck
