Strange symptoms hello , i was in a petrol station last night , got me a full tank of gas when suddenly as i accelerated off the car started jerking aggressively and jumping , i braked and it kept on revving by itself with continious pulses of revs despite the fact that i took my foot of the gas peddle , then 10 seconds later the car was completely fine and i just drove off . I changed the fuel pump last year at around the same time as well as the baterry , what could be causing these problems ?

SOURCE: Car rev up and down at startup, also car jerks at release of gas

This sounds like a vacuum control problem. Since part of the problem is when the engine is cold; a thermal switch is venting vacuum until the engine warms up enough to shut down the thermal switch, thus restoring a steady idle. Vacuum can be affecting high rpms while running too. You could have a misrouted EGR vacuum line opening the valve at the wrong time. There are sometimes hose routing decals on the radiator shroud or under the hood. These can be visibly checked.

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.

Gas tank will not fill up on 2001 ford expedition


Gas as in gasoline or gas as in LPG gas? If its petrol, the fuel sender may be out of adjustment. (Usually means a new sender) If its LPG, the fuel stations are set to automatically shut off at 80% full. The gas tank will never actually be full to the brim but the gauge should be showing full if the gas nozzle keeps shutting off. Have a look on the LPG tank itself, they have a little gauge on them which shows how full it is. I have 2 tanks on my car , when "full" or when the pump shuts down, the tank gauges show just under full but the gauge on the cars dash shows full (2005 BA Ford)

Hello,

Do you have an engine light? Throwing a code?
Just does this at idle or when driving/acceleration?
Acting strange changing symptoms (E.G.--idle to acceleration to black smoke out exhaust, etc.)? Plenty of Gas in tank?

Clog in fuel filter
intermittent fuel pump problem
A vehicle starting sensor (E.G.--Throttle Position Sensor (TPS))
Main computer
Engine Light: Pull Code

I hope this helps.

Lights on dashboard 2 petrol station signs on Daiwoo mousso


Hello,

When the light on the petrol station on the dashboard is on, it simply means the fuel is about to finish and you need to refill the tank.

If your tank is full, the light is supposed to be off, and if your light still remains on, then it means there is a problem with the wiring that leads to the dashboard.

Have your oil pressure also checked and the wiring, if your tank is full and the light still comes on.

Take care

Stalling (The best I could think of to describe my issue)


Hello tirckydad_4: If this problem begun, immediately after filling your gas tank, my first guess based on your description would be that you bought some bad gas. Try adding some fuel cleaner to your tank. This should help, but the only way to get rid of the bad gas is to use it, or siphon it out and put some gas in from a different gas station. As a tip, try to avoid filling up when you see a fuel tanker re-filling the tanks at the gas stations. Theory goes, then when the fuel tanker is re-filling, the gas station fuel tanks, it is sirring up old sediment that usually has settled at the bottom of the tank. Sediment that has been pumped into cars can cause cars to run sluggish.

1993 sentra jerking problems.


I wanted to just give a suggestion...do you go to the same gas station to get gas? My sentra ran horrible because I kept going to this same gas station. My gas would get low and it would start cutting off and trying to cut off. I let my fuel go to almost empty and then went to another gas station to fill up. It hasnt cut of for about 6 months now and I havent returned to that gas station.
