Bogging Down when I mash it - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys,

I've had my 2003 Chevy Tahoe 5.3 LS in my 71 burb and running for about 9 months now. I finally made a decent trip in it tonight and drove about 45 minutes down to Nashville for dinner with my wife for our 13th wedding anniversary. I've actually never had it on the interstate, but once I got on and mashed on the pedal it bogged down and I had to let off for me to be able to accelerate again. It did it several other times when I would get to a certain speed. Obviously a fuel issue, any suggestions what it might be?

FPR, possibly MAF. Can you rev it in neutral without bogging?

Yes, it's fine in neutral. It seems to be only when I'm already going 60-70 and then try to accelerate.

Stuck injector, clogged fuel filter, too tight of a fuel filter.
If your still having the problem tomorrow, feel free to call me if you still have my number.
