2007 with gas engine will not rev up when pressing accelerator and sputters when idling. Fuel pump and filter are OK

  • 2 more comments 
  • dalvinhughes May 07, 2009

    spark plugs are ok and no air problems. Was thinking it may be the fuel pressure regulator?

  • dalvinhughes May 07, 2009

    Do pedal rheostat or throttle motor account for low and rough idling?

  • dalvinhughes May 07, 2009

    Fuel is OK. Could be a sensor unpluged i suppose,,,but where to start. OBD II shows no codes.

    is air entering the system where it shouldn't?
    are all spark plugs firing cleanly?

Water in radiator?

  • Benny Freeman
    Benny Freeman May 07, 2009

    if the gas is freezing up because of not water circulating through, it may not idle well.
    The gas turinng form a liquid into a gas freezes
    If the throttle is too low it might run a little rough. but may not be part of the prob :-)

Check the throttle... If i am not mistaken it could be an electronic instead of cable operated. Check pedal rheostat and possible throttle motor.

  • Anonymous May 07, 2009

    Check plug attached to throttle pedal and throttle body look for corrosion and or broken/loose wires. Only explanation for no response from pressing down throttle.

Acts like it isn't getting fuel, chokes out

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?

I am thinking: No engine light
Clog in fuel filter
intermittent fuel pump problem
A vehicle starting sensor (E.G.--Throttle Position Sensor (TPS))
Main computer
Engine Light: Pull Code
Sensor

I hope this helps.

89 chevy s10 misfires and sputters when i give it gas, dies when i stop. Sometimes it runs fine, but recently it's just been bad. When i rev the engine it can stabilize the idle, but usually die

check fuel pump pressure- fuel filter --air filter --egr valve if carboned up clean or replace and cat converter feel the exhaust if feels restricted may be clogging up

My Toyota Quantum 2.7GL idles but does not rev up. i ve changed the fuel pump and filter but still it starts, idles but does not rev up when you press the accelerator?

We do not have this model in US, but I assume it is a new model 2016-17. You throttle (and the "rev" ) is controlled by the computer. The fact that your car is idles - should mean that your computer is fine! There are two types of idle control: 1st- when you have a bypass of the throttle, which lets the throttle flop stay close while idling and let's the air into the motor through a bypass and electronically controlled idle switch. Inspect your throttle - the electronic/metal unit located on the large pipe through which the air gets into the motor: if you have a "bypass" for the air then you need to inspect your throttle body as it could be your problem.
2. most likely you do not have a bypass and your idle is controlled by your throttle body, then it is sure working fine and your only issue is that your engine computer does not know that you press the accelerator. Your gas pedal has an electrical unit on it which connects to the engine computer- inspect the connector/wires if all looks fine most likely your accelerator sensor does not work- you need to change the gas pedal unit ( I think it called accelerator sensor).
Good luck.

It idles just fine but when you accelerate its sputters and dies if you do not work the pedal. the timing is good.. the Carb is getting plenty of gas. it has been turned up. just cannot figure it out

Can you raise the revs by gently pressing the pedal? That will largely eliminate the electrics or will it just not rev at all? Is the idling affected? Have you checked that the accelerator pump is working as it should, Is the mixture correct? (What did you turn up, the idle speed or the mixture? and is the timing advance working as it should? Is the fuel pump working properly? Make sure it's pumping enough fuel. Failing all that it could be contaminated fuel or a blockage.
You say the carb is getting plenty of gas but it sounds like fuel starvation or excessive richness if you can get the revs up eventually.
Disconnect the fuel pipe to the carb, put it in a deep bowl as you dont want it splashing all over the place and get someone to crank it. It should provide a steady good flow of fuel. Finally check all vacuum hoses/pipes for leaks

Vehicle rev's or accelerates fine when started for just a minute. Then it wont rev up. When you push on the gas it just struggles. Wont really go much above 1500-1700 rpm. idles ok. It is a gasonline...

that sounds like a fuel delivery problem. either the filter is clogged or the pump is not delivering the right pressure. i assume you have no check engine light. this would not set one but other problems like sensors would. being 11 yrs old i would not be surprised if the fuel pump was worn out. good luck

Rough idle, Car shakes, sputters and misfires upon acceleration

It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.

Sputtering at midrange rpm somtimes

Perhaps I'm too late and too long winded! But to answer your question about the fuel pump, yes the pump failure mode could be gradual. But as for your "sputtering" engine the root cause could be related to the fuel or ignition system. For clarification I have a few questions. (1) Realizing this may be an intermitent problem, can you make the engine sputter if you rev the engine with tranmission in park? If yes, this reduces the probability of the sputter being ignition related. (2) When you do rev the engine do you get full rpm's (> 2000rpm) or does it seem choked/limited? If no, your suspisions maybe correct and your engine could have a fuel system problem. (3) Or possibly the sputter only occurs/worsens when the engine is loaded? You can sufficiently load the engine by applying the park, service brake pedal, shifting the transmission into drive, and then slowly applying moderate accelerator pedal. It shouldn't take more than 25 to 50% of accelerator application to safely load the engine.

Two possible solutions: If the engine sputters with the transmission in park or you just don't trust the fuel pump you might want to check the fuel filter first before condeming the pump. The alcohol content in fuel could have cleared enough debris to plug your 3 month old fuel filter. You should be able to blow through the filter without much effort. When the fuel filter is clogged it will fatigue the pump and can lead to failure. It could also be poor fuel quality though. (2) If the engine sputters loaded check the ignition coils and module. One way to check a coil is to disconnect a plug wire set before trying to duplicate the problem. If the engine sputters worsens with a wire set disconnected that coil is okay. You will find the culprit when the sputter doesn't change with a plug wire set dis connected.
