No acceleration when pressing gas pedal

[rdub333]

I have an 04 armada 4x4 with 5.6 V8. Also have nismo cold air intake. I just drove a trip 1500 miles to New Mexico. Near the end of the trip when I would press the gas to accelerate the car would sputter, just sound like vuuu vuuu vuuu vuuu and never get about 3000 rpms and lose speed (or maintain) it even went as far as to lose so much speed to shut off at one point, causing some backfire noises. I've noticed that the lower the gas in the car the worst. When it's under 3/4 tank it does it non stop, but when full, I can get into and and it will rev up to 5000 and shift and keep going. I got a code P0102 (MAF sensor) but I have cleaned it, the air filter is clean and the oil has been changed, with little results. I really dont want to spend 200-300 on a MAF sensor if that's not what it is, and I'm afraid to take it to a shop here because i've lived here for 1 week and dont want to get hosed. Any advice or help?

Couldn't you bypass the MAF using a resistor? It would definitely take care of those times when you are at HIGH altitudes...

If you are still getting the code for the MAF sensor you may need to clean it again. It is important to clean it with a MAF sensor cleaner, not other cleaners/solvents. You can get the cleaner from auto parts stores.
If you are having the problem and not getting the MAF code, then the fuel pump is probably bad or the cats clogged.

I had a very similar issue not long ago but without any DTC. It turned out that the ABS actuator harness connector was full of dust. Once cleaned, the problem disappeared. But as I said, in my case there was no DTC.
