You'll have to check everything in the closed loop. Start with the O2 sensor. Good luck.

What is the fuel pressure specs on a Chevy cobalt 2.2 ecotec 2009


I don't know the exact pressure but 55 psi sounds good to me. Most ordinary passenger cars run at about 2 bar with something like a 5 psi increase for acceleration.
A pressure test isn't a lot of use on its own as it is possible it can provide the pressure when no demands are placed on the engine but not deliver the volume of fuel needed when demands are made. A peak pressure test and a flow test would ensure the fuel system is good.

I am wondering if the egr valve is on the same side as the lean bank? Dodgy egr valves are a big cause of bad running.

1993 Chevy C1500 4.3L V6 TBI starts but dies at idle after warming up.


Low pressure from fuel pump, when the pump is cold the pressure increases, as it warms up the pressure drops (this happens in a pump that is going out) the normal pressure should be at 40 with the key on and engine not running, when started the pressure should stay around 36, any less it won't idle and may run as long as you hold the pedal down. The injectors are opened electronicaly, so as long as there is fuel flow the engine gets fuel to run.So check the fuel pump, soundslike you need a new one

93 olds ciera sputters and no power from dead stop,runs fine when warmed up.changed fuel filter,checked vacum lines and fuel pressure


possibly the EGR is stuck. Does it idle fine and rev up fine in park or neutral, Or does it sputter?

Vehicle starts cold but runs only for about 45 seconds, then dies. No reving just before it dies. Subsequent starts die immediately.


SOUND LIKE PROBLEM IS IN THE FUEL SYSTEM AND TIMING OFF.CHANGE FUEL FILTER HAVE FUEL PRESSURE CHECK.IT SHOULD RANGE FROM 34 - 40 PSI AND 53 - 59 PSI.SHOULD BE NO LOWER.IF FUEL PRESSURE GOOD.HAVE TIMING CHECKED.MAKE SURE PLUGS + WIRES GOOD ALSO CAP AND ROTOR.HAVE INJECTORS CLEANED.ALL THIS COULD CAUSE THE PROBLEM YOU HAVING.

I have a 1995 Chevrolet S10 that seems to be missing on take off but once you get going it quits and runs fine until you come to a stop again and then on take off it starts missing again and then levels...


Change the fuel pump. Check first fuel presure.
fuel regulator. PVC valve stuck????
Check the vacum hoses and EGR.
Clean MAF mass air flow sensor.
check the IAC idle air control resistor.

Stumbling idle, stalls when throttle opens


If the car is running that bad the check engine light should be on and code/s stored in the pcm along with a snapshot of what is going on at the time the code is set. A possible solution is to check the Mass Airflow Sensor or the MAP (manifold absolute pressure) sensor depending on which your vehicle is equipped with. The engine may run until the engine computer switches to closed loop fuel control (means its warmed up and the pcm is in control of the fuel trim) and then stall upon accel. Be sure you have checked all the basics first.

1992 gmc chevy 350 wont idle when warm


This could be a number of things but i think that your problem sounds like a vacuum leak or an EGR problem. Try listening for leaks and try un-plugging the EGR solenoid valve one time.

Sounds like your fuel pump is going out on you. Check your fuel pressure. You should have 40 psi when the key is in "on" position. You should have no less than 5 psi under that when it's running.
