Ok, i have a 91 civic hatch, when then tank is near empty then the car drives good, like it should, and has *****, as soon as i got to the pumps and put in gas, it lags when i step on the throttle and has half the ***** as it would normally have, then after a few days when the needle is back to almost empty then i get power form it again.

 

could it be the added weight of the full tank of gas?

 

Man, 1 liter weighs 1 pound, so i dont think that 13 extra pounds will matter(thats how many liters you get for 10 bucks here), lol, i only put in $10 at a time, however could it be the extra volume of fuel in the gas tank is causing it?

Check your fuel system pressure. If there is, locate the leak and fix it.

Um... I've heard of fuel pumps going bad having the same symptoms you do. See if you can borrow someones fuel pump for the day and see if that makes a difference.

 

If not mistaken... Gas weighs a little less then water does per gallon, thats something like 7+lbs, I go by a 8 pds myself. So having that much gas, would start pulling it down. I can tell by how much gas is in mine, just by the feel too...
