Here goes. 69,000 miles on base 2005 Impala 3.4. It seems the HIGH fuel usage started AFTER all new fuel lines we're installed.(as far as i remember). I can drive 30 miles and it uses about 1/8 tank or 1/4 tank (+ -) for round trip. so 15 miles 1/8 tank.
It runs fine.
Just changed spark plugs due to maybe that was a cause and they were worn out with a larger gap in them across the board. I just changed the fuel pressure regulator today and need to drive it some.
Sometimes a can smell a gas odor mostly not. New fuel filter also. Strange thing is if the car sits for a day the fuel gauge can read LOWER just by sitting...ok,that's crazy!
NO...i repeat...NO leaks underside with it running or not. Fuel pressure is fine.
It has run a bit lumpy at idle, it has taken a bit longer to start in the past (a few reasons i changed the F.P.R.). Mostly it has run very smooth where you would think it's not even running!
Plastic fuel tank so did the last shop maybe get a small crack in it when removing it for new lines ???
The passenger side tank strap is bad looking, the drivers side looks new.
(live in the snow belt).
There is NO dripping anywhere so where in the frigging world is the gas going???
I ran it today...shook the car to get the fuel sloshing in tank and no see leaks.
Been doing this for about 5 months or longer and oddly it seems AFTER the tank was dropped for new lines.
Had engine scoped...checked. All sensors are working in range as they should.
Many are stumped. The more fuel in tank the faster IT SEEMS to go out yet tank looks good...."looks good".
Thoughts ???
New tires within last 9 months. Drives straight. Brakes...well make some rattling sounds on/off.
Wheels spin freely.
I did have BOTH front hub/bearings changed with Moogs and BOTH drive axles. Just some fyi.
It used to not use much gas but...when it wasn't so old as it is now.
It does need the fuel filler neck/tube...it's real rusty !!
OK...Your turn !
