ECM is good as it is doing the job
it is sensor problems such as accelerator position, throttle control motor/sensor, MAF/VAF

SOURCE: no acceleration

I had the same problem with one exception. It would rev higher than 3500 but the higher it revved the more it bogged. I had the catalytic converter replaced. I thought I bought a new car. Acceleration is just like new. It was easy enough to test. My mechanic cut a hole in the exhaust pipe in front of the catalytic converter. It sounded like a truck but the acceleration difference was immediate. Easy diagnosis.

The car is hard to shift because the more you press on the accelerator the more the computer for the transmission won't let it shift. Which in turn causes the car to bog more sending more unburned fuel into the catalytic converter. Which in turn causes more carbon build up and more back pressure. Vicious cycle. It will only get worse.

My thermostat caused the entire problem. Thermostat was stuck open, engine never got to operating temp most days. Car burned rich. Bad gas mileage. A lot of unspent fuel being dumped into the converter. Probably have some underlying cause that needs to be addressed. Bad plugs, wires, coil, fuel filter.

SOURCE: 1998 s10 bogs down when i press the gas hard...

Check your fuel pressure it should be between 25-35. If you do not want to test it then just replace it. If you have to spray gas into the throttle body and it runs great when floored then you are not getting sufficent fuel to your engine and that is the fuel pump

SOURCE: 1997 dodge dakota v6 engine wont start replaced

turn the key to the on position a see if you can here a buzzing sound around the fuel tank,if you don't hear a sound then. (be very careful while doing this) with the key off take a fuel line coming from the tank loose,make sure its pointed away from you and turn the key to the on position,see if any gas comes out,if not then your fuel pump is probably bad.

MY VW SHARAN 1998 POWERS OFF WHEN I SLOW DOWN.


This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.

1998 beetle will start and idle, but will die when accelerated


When was the last time you had your fuel filter replaced ?? Sounds like the engine may be starved for gas because of a clogged fuel filter. If you have no record of having been replaced, this may be the least expensive place to begin, but be careful the quick disconnects on the fuel filter can be difficult to push in. Also, the fuel lines will be pressurized when they are disconnected, and could spray gas into your face if your not careful. If you damage the disconnects on the fuel lines you will need to have the lines replaced, so be gentle.

My 2001 new Beetle will not stay running. It starts up, then 5-8 seconds later will sputter out and die. If I pump the gas peddle a bit after it starts, it trys to stay running longer but then sputters out...


Hi There,
Try this: You will need 2 people - Have someone Spray Starting Fluid in the throttle then start the car and have someone spray the fluid continuously into the throttle. If the car continues to run you have a fuel problem, but if it stalls out, replace the coil pak. Hope this helps and thank you for using FixYa!
