car runs normally, after runs and turn ir off, when I start it again, runs 3/4 blocks normally, then stalls, RPM fluctuates between 700/1200 RPMs even with gas pedal full, if I turn off and start on again, does the same, only way to run again is leaving car idling for 5 minutes (by clock) or keeping gas pedal pressed for the same time, then car runs almost normally.
does anybody know which problem is? does it something as fuel pump/injectors related?
thanks to everybody

 

May want to check codes, while the car is running, although with a problem like that, its a shot in the dark.

 

Start by doing a general maintance/repair on the car.
Replace airfilter, fuel filter, spark plugs, plug wires, check for broken/leaking vacuum lines, change the oil.

If that doesn't fix it then it could possibly be wiring.

 

Reset the computer.

 

I'd check TPS and AWS first, then the BAC.
