It will start but almost immediately sputters and dies. Can not keep it running. Gas pedal is hard to push down when trying to rev the engine a bit in park.


Sounds like it's time to replace fuel filter, or possibly a bad fuel pump. I'm uncertain why the gas pedal would be hard to push as it most likely isn't a cabled type on that new of a vehicle, but you can check by looking at the top of the pedal itself to see if there is a cable and if it's possibly frayed.

Car surging


Is the car equipped with the Automatic Transmission?
If so, read on.
Otherwise skip to the end and answer some questions.

POSSIBLE SCENARIO:
I have observed a condition where my car surges slightly when the torque-converter clutch (TCC) cycles between lock and unlock when driving on an uphill grade.
First some basics and history that will explain why the TCC is used.

Engine, Torque Converter, TCC, and Transmission relationship--
The TCC allows for a solid connection between the engine and transmission which allows the input to the transmission to rotate at the same speed as the engine.
Without a TCC, there is slippage between the engine and automatic transmission. The slippage is greatest at low engine RPM. That is what allows the engine to run with the automatic transmission in gear, like when you first shift into gear or stop at a stop sign. When the throttle pedal is depressed, the engine RPM begins to increase and the torque converter begins to slip less and less the more the engine RPM increases. The car moves. But even at cruising speeds the torque converter slips slightly. Engine RPM is greater than transmission input RPM, which is realized as slight decrease in fuel efficiency.
When acceleration is complete and a constant speed is being maintained, the engine power output is reduced to the point where the TCC can engage and eliminate any slippage between the engine and transmission. If the car has a tachometer the engagement of the TCC can be verified when a slight reduction in engine RPM observed without a corresponding change in vehicle speed.
One method used to test the operation of the TCC is as follows:
Find a flat section of road where it is safe to perform the test.
Reach a steady speed and keep the gas pedal depressed with one foot. While observing the tachometer (or listening for an increase in engine RPM), with the other foot depress the brake pedal enough to activate the break light switch but not enough to engage the brakes. When the brake light switch activates, the TCC receives a signal to disengage. With the gas pedal being held steady, release the brake pedal and the engine RPM should decrease when the TCC engages.
Old cars with Automatic Transmissions did not use a TCC. I believe the TCC was put in use in an attempt to increase fuel economy.

MY EXPERIENCE WITH SIMILAR SYMPTOMS
The condition that causes that issue on my car is this:
- A slight uphill grade increases the load on the engine.
The car tends to gradually slow and it is necessary to depress the gas pedal to maintain speed.
- Depressing the throttle pedal (manually, or automatically with cruise control engaged) signals the torque converter clutch to unlock when the load increases slightly. (A more drastic load increase would signal the Transmission to downshift to a lower gear.) The corresponding increase in engine RPM and output is enough to compensate for the reduction in speed. When the vehicle speed, engine RPM, and throttle position stabilize to the point that the TCC will engage and the engine RPM will reduce in correspondence with TCC engagement. Now, if the road conditions have not changed, power output is not enough to maintain vehicle speed. With the increased load caused by full engagement between engine and transmission, and the cycle (surging) repeats itself until the road conditions change.

Does that help?
If not:

QUESTIONS
Please define the symptoms.
What are the road conditions when the surge occurs? (A slight uphill grade?)
What is the frequency of the surge?
Does the engine power output have a noticeable surge?
Is there a speed change related to the surge?
Does the tachometer move up and down with little or no change in vehicle speed?
Are all instrument indication in the normal range?
What else has changed?

Good luck!

Hi. This cold and windy morning, with less than 1/4 tank of gas, my manual 2002 Accord wouldn't start. The starter would crank, but that was it. After a few tries, the car DID start, but then died. ...


you may have a frozen fuel line. fuel not reaching engine. put some dry gas in it to displace moisture in fuel system. the reason why it quit when pushing pedal is, its starving for fuel. have a good day !!

You just need to go through a simple Idle Relearn Process.

The Idle Speed Control motor will cause the accelerator pedal to tap and the car will surge back and forth, actually acting like there is a lack of power during intial startup.


Whenever a battery is changed, went dead or the ECM computer is replaced.

In order to make the engine run normal again, you need to take the car through a relearn process. Otherwise the idle could be very slow or have a 30mph idle.

To enable it to relearn, here's what to do.

1) Disconnect the battery cable for 15 minutes, before hooking it back up.

2) (KOEO) Turn the Key On with Engine Off, just so the electronics are on, but without starting the engine and turn the climate control panel to off.

3) Push the off and warmer buttons on the climate control panel at the same time and hold for up to 5 seconds for the computer to go into diagnostics.

On the fuel panel screen it will display 888 then E52 and then 70.

When it gets to 7.0 shut off the key for 1 minute.

4) Repeat step 3, two more times.

5) Start the engine without pushing on the accelerator pedal and let it run for 18 minutes with the climate control panel off.

6) After 18 minutes put your foot on the brake and shift into drive and wait 1 minute.

7) Then turn on the a/c by pushing the auto button. It needs to be warmer than 60 degrees F so the compressor can engage. Wait 1 more minute.

8) Put the shifter back in park and turn the key off.

9) Wait 1 minute

10) Idle relearn is now complete and the engine should start and run correctly.

Engine surges and shuts down


When your running out of gas the dirt, grime, and gunk is all you have left except water and that may cause it to surge then slow down irrelevant to the gas pedal pressure.
I've had a similar problem when I ran out of gas
I would try a can of expensive fuel cleaner and a can of dry gas before anything else but that's just me!
