97 expedition has intermitting no start. Thought it was fuel pump so replace it. It will start but as soon as touch gas it spits and sputters then dies When it does start it may run fine ,plz help.


Monitor the fuel pressure with a test gauge, if that is OK then try disconnecting the MAF sensor and see if it will run better (the computer goes into limp mode), if it does the MAF is likely defective. Don't replace any parts until a certified technician verifies the issue, you have wasted enough money and time already right?

Why does my 98 subaru legacy sputter and die?


Clean your MAF sensor and throttle body. If it's dirty it will send wrong voltage to ECU, running either too lean or too rich, most likely too rich and flooded the fuel injectors.

Recently replaced fuel pump due to nissan truck not running. When it starts it sputters and dies when you give it gas.


Sounds like a vacuum leak or crossed vac lines, MAF or MAP sensor issue. Check fuel PSI & fuel volume.

When I press the gas, it reves, but then sputters and jakes. I push the gas on the highway, and it won't speed up. It's like it has a mind of it's own, and will sooner or later give me speed, but then I...


If you have a check engine light on, you'll need to get the ODBII code to have a clue of the problem. If there is no code, I would start with changing the plugs and plug wires. Next I would try cleaning or replacing the MAF sensor. The MAF sensor is located on the throttle body. Here is a picture of my 2002 Impala 3.8L MAF sensor (ignore the radiator and hose):

92 yukon sputters at takeoff


is this a missfire? have you replaced the MAF sensor which is a common cause of this, if over 100,000 miles replace plugs and plug wires as well.

My car idle dips to low RPM at a stop i give it gas it dies


Is the engine light on? Check the air inlet hose between the throttle body & MAF sensor for cracks or leaks. Try unplugging the MAF & see if there is any difference

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!

Car sputters or dies when idling, but starts fine.


I suspect you have an idle circuit issue. When the thottle is closed, the throttle valve is almost closed (like 95%). The linkage on the throttle body is against the hard stop.
SO, when idling you need a way to let enough air into the engine to maintain an idle speed. The IAC, Idle Air Control valve is the way you do that and the engine computer controls the rate of air flow.
Sometimes it gets plugged up so you can clean it with a little carb cleaner. Might have to take it apart.
Also, you have a MAF, Mass Air Flow sensor that tells the computer how much air is flowing through the air cleaner intake at any time. The sensor gets coated with varnish and vies a false reading. Clean it gently with carb cleaner and a toothbrush.
Other than that, I would go to an auto parts store that can run a computer scan for free to see if you have any fault codes stored. They will tell you next stpes.

I assume you 2.0L SPI engine & not Zetec.

  1. Disconnect the idle air control (IAC) valve electrical connector (air cleaner outlet tube removed for clarity).
