You overfilled the tank and screwed up the fuel vent canister. Usually the car will not run, dies while idling, or surges if you try to drive, also if you try to fill up again you might find it difficult to fill your tank fast because the canister is not venting the tank

SOURCE: seems transmission gear shift problem

Pull the distick and smell the oil. If it's discoloured (black or dark brown) you know the transmission friction plates are burnt and needs a rebuilt.

SOURCE: high rpm at idle: code P1294 target idle not reached

Hi Rodrigo, The idle control is activated by the temperature sender unit. It sounds as though yours is giving a cold signal to the computer and it pushes up the idle speed to compensate as if it has just started. The sender unit is a different unit from that which operates the gauge on the dash instrument panel. Replace it and I believe your problems will be over.Regards John

How can you tell if you have bad gas in your tank


What are the indications of bad gasoline?
A:

QUICK ANSWER

The symptoms of bad gas involve a lean misfire, which creates a P0300 code in newer cars, engine detonation and pinging, sputtering and stalling. These occur because the bad gas fails to keep the fuel system clean and introduces contaminants that can clog fuel filters, fuel pumps and fuel injectors. In addition, bad gas can have an octane rating lower than advertised, leading to the aforementioned detonation and pinging.

FULL ANSWER

Receiving bad gas from a fueling station is more common than the industry admits. The only cure for fixing bad gas is to drain the fuel tank and fill it with fresh gasoline while cleaning the fuel system in the process. Bad gas can be caused by gasoline suppliers not mixing the required amount of additives in the fuel, causing them to be less effective in preventing deposits and causing fuel varnish to form in the fueling system. Sometimes the tanks, whether at the fueling stations tanks or in the vehicle's own fuel tanks, are contaminated with dirt, corrosion and water. Because no filtration system is absolutely perfect, even with the various filters and stringent EPA requirements in place, these contaminants end up inside the car and may damage it. Gasoline that is lower in octane often occurs because either the supplier or the fueling station intentionally sells regular fuel as higher octane, profiting over the difference in price.

How long ago did you have the engine tuned up? Could be that that the engine needs a tune up. If it was running fine and then all of a sudden it started running bad then it could be you purchased some gasoline with water in it. Don't buy gasoline if you see a gasoline tanker truck at the gas station and the tanks are being filled.. All that is happening is the gas going into the tanks is sturring up the dirt and debris in the tanks. Kind of like stirring kool-aid in a glass of water. Also worse is if the tanker truck is there and the tanks are being filled while its rainning or been raining all day with lot of nice water puddles were until the caps were removed to fill the tanks from the tanker and the water fell in the tanks. If its bad gasoline that is making your car run bad, you can buy an additive at the auto parts that you can pour in your gas tank to help burn the water out of the gas. Hope that all you need is the additive. Good luck.

Is difficult to fill gas tank


Gas pump nozzles have a device in the end that when gasoline runs back up into it, it turns off the fuel flow." There's a tiny hole near the bottom of the gas pump nozzle connected to a small tube.
Normally, air flows through that tube while you're filling and the gas keeps flowing as long as you hold down on the trigger. When that hole gets covered by gasoline (when your tank is full), a vacuum forms inside the nozzle and an automatic shutoff switch gets tripped, turning off the flow of gas with a thunk. Next time your fueling up try to reposition the nozzle.

When putting gas in my 2004 Kia amanit the fuel nozzle kicks off. How do I locate and fix the problem


HI Bridgette,

Due to the different shapes of fuel tank filler necks in cars & trucks, it may be necessary to vary one or more things to allow fuel to flow uninterrupted until the tank is really full.

The main problem can come from the new "vapor recovery" gasoline pumps. These pumps and hoses actually recover gasoline fumes from your tank as the liquid gasoline displaces the air / fumes in the tank is it is being filled. If gasoline flow is started at full blast, it can splash back slightly, causing liquid to be pulled back by the pump - so it shuts off. So, start with a slow rate of filling and gradually increase flow rate to maximum over 5 to 10 seconds. If it still shuts off, try some of the suggestions below.

First, don't fill at maximum flow rate from the pump - that is, don't set the nozzle for wide open. Select one of the other "latches" on the handle instead of the fastest flow and let the tank fill entirely at this rate.

Second, you should experiment a bit with the length of nozzle that you push into the tank's filler neck. If you push it in too far or too little, the pump nozzle can do what you're describing.

Third, try twisting the nozzle slightly so that it doesn't hang straight downward - a little to the left or right may provide a solution.

Lastly, try a different gas station. Their pumps may not be so picky with your tank's filler neck.

Good luck!

When I fill the car up, at some point, fuel spills out before the fuel flow stops automatically as it should.


Hi, probably a clog or mis-positioned vent tube in your filler neck. FYI--- filling your tank on the lowest pump speed will give you more gasoline upon fill up. The higher the fuel delivery rate, the more fuel is vaporized in fumes coming out of the gas pump. Pumps are equipped with vapor recovery, so around 3% of what you are paying for is actually recovered and returned to the station's tanks via vapor recovery. Lower delivery speed reduces vapor, so you actually get more of what you are already paying for. Also, fueling when the air temp outside is lowest (early morning and late evening) produces less fuel expansion and less vapors. Fuel expands with heat, therefore you lose 2% per 10 degrees of heat due to liquid expansion. Lower speed will also help with your overflow issue.
Please rate this answer! Thanks, Mike

NEVER LET A CAR WITH ELECTRICAL FUEL PUMP RUN OUT OF GAS BECAUSE FUEL PUMP WILL OVER HEAT AND BECOME DAMAGED.GASOLINE KEEP FUEL PUMP COOL AND LUBRICATES IT.IF GAS TANK RUNS DRY FUEL PUMP WILL OVER HEAT AND SELF DESTRUCT.

When I go to fill up the gas tank the gas keeps cutting off at the pump handle and I have to slow the gas pump to a trickle in order to fill the tank.


The problem is that your gas tank "pushes back" like it's full even when it isn't and makes the fuel valve click off. Tom and Ray on Car Talk covered this in a 2007 show and I pasted some of their response below:

"RAY: This condition is probably caused by either a blockage in your gasoline vapor recovery lines or a bad refueling control valve.

TOM: Gasoline vaporizes. How do we know that? Well, when gasoline is spilled, you can smell it, right? What you're smelling is vaporized gasoline.

RAY: And in the old days, when you filled up your tank, all the air inside the tank -- the air filled with gasoline vapors -- came whooshing out through the filler hole or through a vent at the top of the gas tank.

TOM: But then people in places like Los Angeles realized they couldn't see the person standing next to them due to smog. And since gasoline vapors contribute to smog, car makers were forced to install devices to capture those vapors.

RAY: So now each car has a vapor recovery unit that collects the gasoline vapors from the tank and then, the next time the car is started, sends them to the engine, where they're combusted. Your vapor recovery system isn't working, Lottie. One possibility is that one of the rubber hoses is blocked or collapsed."

Sluggish and loss of power


if the car ran good befrore you filled up ,there might be water in the fuel you pumped into the car,sometimes water gets into the gas station fuel tanks when it rains,try to drain your gas out and try fuel from another station

Gasoline pump at gas station keeps turning off


There is a vent valve located near the fuel tank. The vent valve is part of the EVAP emission system. If the valve is obstructed or failed, air will not escape while refueling.
Has the service engine light come on at all?
