Have a problem and need help. My 99 Yukon is stuttering under load. When I am accelerating or going up hill you can feel a stutter to it. I am no expert so I was looking for some help. Also starts really hard when warm. When cold fires right up. Was wondering if this could be the fuel filter has 130,000 and filter has never been changed

Well for a start you need to change the filter. It calls for a change every 15 to 30K or so. I usually go about 50K on mine. Also, clean the throttle plate. Change the plugs. basic stuff!

Check this website for computer updates for your truck. http://calid.gm.com/vci/VINEntryPre.do Input your VIN and see if there are any fixes for drivability issues that can be solved with a reprogram of your vehicles computer. But I totally agree with above, except the fuel filter should be changed on our trucks every year or 12k Miles.

By the way, the dealer would be the one to do the reprogram, sorry, thats how its got to be.

Not that I would disagree as to the frequency of the fuel filter change, but IIRC on late-model year NBS trucks, that would be a somewhat expensive proposition--especially if/when done at such a frequency, and if you're not too keen on performing the task yourself--since I believe the fuel filter is located inside the fuel tank...

The fuel filter is along the frame rail on the drivers side.
A hard start when warm can be the fuel pressure regulator. My neighbor has a 97 Yukon that had the same problem. I hooked up my fuel pressure gauge and we turned on the engine. Pressure was 60 PSI (this is good). As soon as he shut it off, the pressure dropped. Within a minute is was only 20 PSI. It should have held the pressure.
He had the fuel pressure regulator replaced and the hard starting when warm went away.
A bad fuel pressure regulator can also explain your stuttering under load if the pressure is below the required pressure.
The pump could also be bad. Not replacing the fuel filter could have put a strain on it and it is on the way out.

Yes...but I thought I read somewhere that on recent-vintage ('04+) NBS trucks, the filter was either inside the tank or somehow integrated into the fuel pump. I could be wrong, but that's what I read somewhere...

I should specify that I do not know the exacty interval for the New Body Style trucks from 2000+ , I was actually referring to the 88-99 series trucks.

You read my post a long while back..... The fuel filter in the late 03 to now current fullsize GM's are in the tank with NO sched. maitance interval to replace! Is that crazy?! Anyway the poster asking the question has a 99.... this means its a super easy change (albeit messy) along the drivers side frame rail.
I (up until I bought my 04 yukon) ALWAYS replace my filter annually. It is recommended you do so per manuf. instuctions. All good mechanics will also tell you in high pressure FI systems, the filter should be replced 12,000-15,000 or annually. It is amazing how much dirt/black colored gas comes out of a filter when you replace it Again, the new trucks -no filter to replace; its in the tank now and is replaced when you change the pump.

Understood...I was referring to your previous statement about having it changed on "our trucks"; maybe yours, but not mine...not for lack of trying or wanting on my part, though... :smokin:
