car stalls under acceleration...???

[CBboY126]

does anyone know what this means?...when i push the pedal down enough for my auto LX to shift down twice the engine stalls and the CEL comes on.....but then..i can turn the car off and the CEL wont come on and everything runs like normal....can anyone help me with this?? thnx in advance...i need help quick

When you press the accelerator does the car misfire? My LX had a similar problem that it would loose power around the 2000-3500rpm band and it would stall and miss fire... almost like going in neutral. The problem would randomly come and go. Turns out it was a faulty Oxygen sensor.
Though, could also be other things like a vacuum leak(though I doubt it, since this should be a constant problem), clogged gas filter... or clogged EGR valve and port?
I would suggest waiting to wait for the second opinion of others, since I'm still new to this sort of thing.

The CEL is stored on the ECU memory. Pull the code and tell us what it is. I'm suspecting Code 1 or Code 43 , but check it out.

yea thats what i was wondering also...the codes i get are 16 the fuel injection system and 12 the EGR...

Hmm , fuel injection malfunction maybe?


For the CODE 16 – Fuel Injectors.

CAUTION: Gasoline is ultimately flammable , use high precaution and have a fire extinguisher in hand in case of emergencies.

Fuel Injectors – supplies fuel to the combustion process.

What to do: While the engine warm and running , unplug one fuel injector electrical connector and see if the engine speed changes. If a certain injector fails to change the idle speed , check the electrical resistance. If all fuel injectors change in the same idle speed , injectors are working correctly.

To check fuel injector resistance , using an ohmmeter. Turn the vehicle off and unplug each fuel injector electrical connectors. Resistance should read between 1.5 to 2.5 ohms. If the acquired reading is not within range , replace the fuel injector.

To replace the fuel injector you must relieve the fuel pressure and disconnect the negative battery terminal. In order to relieve fuel pressure , you'll need two wrenches on this process. One for the loosening the service bolt and second for holding the banjo bolt. Be advised that fuel will come out during this process , it is good to have lots of shop towels in hand. Loose the service bolt to relieve pressure , once it's relived remove the service bolt and install the bolt back with a new washer. After the relieve process , you can now remove the fuel injectors. To remove the fuel injectors , unplug each electrical connector , detach the vacuum hose and return hose from the fuel pressure regulator. Remove the ground cable located on the fuel rail and remove the fuel feed line. Remove the mounting nuts and remove the fuel rail from the injectors. You can now remove the injectors. Install new injectors with new seal rings , o-rings and cushion rings. Installation is reverse of removal.

EGR , I would try just to clean it first.

yea i boubt its a vac leak i just swapped my blown motor for another f22a1...and my EGR seems o be workin correctly i dont know why im gettin that code..also i have to check my injectors

I had the same type of problem with my Chevy Corsica and it turn up being the TPS (Throtle Postioning Sensor) Might be a cheep Fix!!
