Question about 1984 Toyota Celica

1 Answer

Car has been idle for 8 months - is gas still good?

If the car has been sitting for 8 months to a year, do I need to clean the gas tank before I turn it on. In other words, how long can gas sit before it deteriorates to the point that it may clog up fuel injectors or cause other problems?

Do I have a bad fuel pump


Not symptoms of a pump. Sounds more like a bad idle air control valve. run some fuel system cleaned in it and run a full tank of gas to see if it changes.

I was needed for a medical emergency in Florida and left my 2000 Eclipse sitting idle outside 5 months, from winter to summer. The gas tank was full and I didn't have time to stabalize the fuel before...


If I were you, just take out the old gas and put some fresh fuel in. Next time, keep a few cans of SeaFoam in the car. It stabilizes the fuel for up to 2 years (1 oz for each gallon).

I have a 1991 Honda accord ex..it has been sitting for years now it wont start where should I start I was told that the gas turns to funk after sitting for a long time.


if it is posible for you to drain the the old gasoline out and refill the tank with fresh gasoline that would be great, but if you only have a1/4 tank and draining the tank is not posible fill your tank up with supreme gas not regular the better grade gas with the high octane will dilute the old gas and help burn off the gas when the car starts.if you have more then 1/2 a tank try to pump out the gas with a driil pump, you can buy these a your local hardware store insert hose in filler neck of the tank.you should also remove the spark plugs and with and oil can add 8 good pumps of the can of motor oil in the cylinders do not replace plugs **** with a freshly charged battery turn the engine over few time in 2 or 3 second intervals this will kleen any rust that would have built up on the cylinder walls and also lube up the cylinder wall so that at start up the cylinder wont be dry ,add a few more sqirts of oil between turnovers.Replace spark plug if old ones look bad put spark plug in and start her up its going to smoke a bit at firts **** it will stop after the oil that was put in the cylinders burns off,let the engine idle for 10-15 minutes before putting any strain on motor give it a chance to clean out cylinders burn a few tanks of gas and change gas filter it should be fine.

As gasoline sits idle for that length of time, it turns into shellac.
this in turn plugs up the orifices in the carb, use a good quality carb cleaner, or fuel injector cleaner as the case maybe. follow the directions carefully. You may have to do this a couple of times.
Good Luck

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.

I left my car for 4 years and when i started it the idle became unstable. in the reverse mode the idle drops to zero. i changed the spark plug and adjusted the ecu and it fixed the problem after using it...


Leaving a car sit that long isn't the main problem. It's the gas.

Over time it thickens and turns to a varnish like material that can gum up key components (like your injectors, fuel pump, fuel lines, etc)

I'm surprised the dealership did not comment on this.

At any rate, the first thing to do is lose what gas is still in the tank. Add OCTANE BOOSTER and Injector cleaner and fill it with High-test. Then drive it around for a while.

Hopefully that will have an effect. I'm trying to avoid surgery on the fuel system. Hence the more passive approach.

Best of luck

did u use fuel stabalizer? if not the gas can turn into a varsale like substance that can clog fuel filter and reck injector seal's, also check the disributor cap and rotor for condensation, this can happen over a period of sitting

My truck will only idle what to do? Do injectors plug? This truck has been sitting for at least 3 years. I drained the old gas and added new. The fuel pump has pressure.


Good chance that the fuel line/injectors/etc. have a varnish on them from the gas evaporating over time. Needs a good cleaning. Suggest something better than just pouring something in gas tank.

Not
