Wade – Sure sounds like a fuel pump to me.

Toyota Tundra (2005) fuel – accelerating problems.
From a full tank of gas until it is half full, I have no problems with accelerating. The truck runs like a scared rabbit!! Problems occur when the gas tank is at half full or less. When accelerating (aggressively), the engine hesitates. The engine rpm will drop from 3,000 rpm down to about 1,500 rpm rather than accelerating to 4,000 – 5,000 rpm. There are no fuel filters (according to the dealer) that could be plugged. I thought it was water in the fuel and have run 3 tanks of gas with ‘Water in Fuel’ remover. I have also run a couple of tanks of premium gas with no changes. The next item to look at is the fuel pump unless someone has a better idea (and cheaper).

Jeremy, I have learned. That’s why I use the fuel the owner manual recommends. That’s also why I drink tap water instead of $10 per gallon bottled water like so many “hip” folks do.

the manual says 87 is recommended but also says premium was used in testing

There is NO reason to use premium gas in a vehicle that is designed to use regular (87 octane). The detergent levels in gasolines is federal directed and is enough in ALL grades to keep vital parts deposit free, especially in “top tier” gasolines. Pay attention to your owners manual and use as directed. These folks designed the vehicle and know best. Save your money in both gas choice and additives.

the other two comments are very good. the reason premium can increase gas mileage and power is that most new trucks have almost 10 to 1 compression ratio which will cause detonation and blow holes in the pistons. to stop this a knock(detonation) sensor decreases the ignition timing only when the truck is working hard. like high speed, high heat, towing, wide open throatle(wot)etc. priemium fuel stops detonation. and can let you get better Mpg and power.

ACTUALLY I have found after testing this out 3 seperate times that premium gas gives me 2 mpg better at 70 to 75 mph. I average 20.9 mpg at 70 to 75 mph from Central Louisiana to East Central Texas on I-10. I got that EXACT reading all three times. I tested the same trip 3 times on regular and averaged 18.4 for the 3 trips. Same speed, Same direction of travel (west), Using only Shell brand fuel, and I alternated the tests between premium and Regular. I drive a 07 Tundra DC 5.7L stock. If you run through all the math at a 20 cent a gallon bonus cost per gallon it cost me 4 bucks extra but I can go about 50 miles farther on the same 20 gallons netting me a better than $6 savings so I make $2 per tank. now if it is a .25 or .30 per gallon extra cost it washes out the savings but it is a economic savings most of my time to put premium in. I owned a 01 RAV 4 before I purchased this truck and it would average about 1 MPG better. My only guess for this is that the VVTI can adjust itself for better use of the Premium.
