If it is stalling remember that idle speeds are determined by the idle speed motor and the amount of air that passes throught the throttle body when the throttle blade is closed(gas pedal released). There may be dirt in the throttle body or there may be a problem with the idle speed motor sticking, both can be cleaned. If you turn the ignition key to on, then off, on, off, on you'll see the 'check engine' light flash codes, this is something you can do yourself and is fairly accurate for checking for hard fault codes for that model year. There may be a code present.
The key procedure should be done within 5 seconds. As many times as you want.
The idle speed motor is called an IAC motor and the code for it is code 25.
This is two short flashes followed by 5 short flashes. Look for codes 15(speed sensor), code 21(o2 sensor), code 24(throttle position sensor-TPS), or 25. a 55 signals the end of the diagnostics. ok? If the injectors were just replaced recently, it really should be re-checked.
