Start problem after filling gas tank

After filling with gas the engine will start but will not idle. It will run at about 3000 rpm and I must put it in gear at this high rpm and drive about half a block before it runs normally until the next fill-up.

Interesting,
is the check engine light on, and have you checked the computer for trouble codes ?
Sounds like the idle air control valve is sticking but that would not have any effect with the gas tank.

SOURCE: fill up with gas

i had the same problem, you have to change the perge control valve, its on the back of the engine below where the plastic intake pipe meets the metal intake manifold on the back side of the engine between the engine block and the firewall, on the underside of your car hood you will see a vacume system diagram, it will illistrate where the valve is, it should cost about 30 bucks or so at a hyundai dealership

My 1998 citation developed some kind of fuel fault. Check engine light came on, this shortly after filling with fuel whilst engine running. Oil pres temp and volts remain good but shortly after that e


First, never gas up while the engine is running it's a fire hazard to you and everyone else at the station. Did you check air to fuel ratio? Is car getting enough of each? The check engine light came on at gas station because of the car running, just like a loose gas cap can trigger it.

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

Hi guys...my yaris is running rich, has poor gas mileage (360km on a full tank). and very slow and choppy idle (idles like a really old car) these are the things i have done so far : change air and fu


Do the following:
1. Clean the throttle body from inside.
2. Adjust the spark plugs gap to 1.00 mm.
3. Check fuel pump pressure. (44 Psi - 49 psi)
4. Remove the negative battery terminal for 5 minutes.
5. Connect the battery terminal.
6. Check the engine oil level and coolant level.
NOTE: Before starting the engine shut off all lights and loads for example room light, blower, radio, parking light etc.
7. Start the engine and hold the throttle at 3000 rpm till radiator fan comes on.
8. After the fan comes on release the throttle pedal and let it idle for 10 minutes.

Hello, my car has sat for about 8 months, 4 months into it, I started it up and once the engine warms up, the idle begins to fluctuate between 1100 and 2000 rpm, up and down up and down it does not do this...


Gasoline left in a cycle or lawn mower over the winter months tends to not burn as clean as fresh gas and eventually will gum up the spark plug, making the engine run rough or hard to start... it's best to drain the tank if you aren't going to use the fuel in a couple months... the colder temperature may also cause the fuel to become less potent, it also turns a darker color I and suspect it may be due to evaporation.

There are products when added to fuel (gas/diesel) to make the fuel more stable over longer periods of time and even renew fuel that's aged...

This is an article I found on gas. I have had this happen to me and if the gas goes bad in lawn mowers I'm sure the same thing will happen in cars just not as common due to cars usually don't sit around.

I would try putting a gas stabilizer in and run that tank of gas till almost empty then fill it and see if the problem is still there.

Also take a look under the hood and look at the wires and vacuum hoses animals seems to like chewing on them some times.

If none of this works repost but let us know if the battery was dead at any time and if the check engine come on while the engine is running.

When starting, engine will rev up to 3000 rpm then will die. but you can keep it running if you keep it revved up above 3000 rpm


Things to look for: Could be your intake manifold gasket, throttle position sensor, vacuum hoses, throttle body gasket, idle screw, fuel pump, fuel filter, fuel pressure regulator, or maybe you have a split in your gas tank or fuel line(s) that is messing with your fuel pressure. See if you smell gas back near the driver's side rear wheel.

Good luck, those are things I would search for, I can't promise anything, could be a number of things. You should have a check engine light on.

Hi, I have a 2006 Altima with 31,500 miles. Recently, the engine start shaking when car is Idle but I still feel the shake when driving or at red lights. My second problem is a weird loud (humming) noise...


You don't need to change the spark plugs since it has only 31.5 K. The plugs should last 60K. There is a an adjustment at the gas cable end at engine to increase the idle a little bit. You can increase rpm at idle to 600 RPM. Since your RPM at idle is low that why it is shaking at idle, red lights. Let me know it it is shaking at high speed ( 2500 RPM)

Low idle, also engine runs alittle ruff after fill-up.


Sounds like the fuel pump is starting to go, the problem after fill up is most always related to a failing pump. The other issue may be a dirty throttle valve.

Ran real low on gas


it sounds like you plugged your injecters put some STP gas treatment with injecter cleaner into the gas tank with at least a half a tank of gas and then finish filling it up and if this helps also replace the fuel filter

Sounds like bad carbon build up, have you tryed using fuel injection cleaner yet? Because of the buildup, I would suggest putting it in with only a half a tank (to get a higher concentration of cleaner vers fuel). Once in, run it down the highway (the cleaner works best when the engine is hot) until you are almost out of gas, then fill it up and add another bottle of injector cleaner (alway add the injector cleaner after filling as the cleaner will foam if added before and this will lead to gas spillage at the pumps). Run the car normally. If it is just carbon, by you next tank of gas the problem should be solved. As pervention, I recomend using fuel injection cleaner every 4 tank fulls (for most people it works out to about once a month).
