Okay, i have a 2000 daewoo nubira and when i put on drive and i start driving my car starts stalling,like starts losing power and when it gets to 50-60mph it gets worst, and ive change the sparks, the cable sparks, and the gas filter, and then gas distribute.. and the gas sensor..any ideas???
It could be many problems:
MAS (mass airflow sensor)
IAT ( inlet air temperature)
IAC (idle air control valve)
TPS ( throttle position sensor)
Check fuel injectors too
The IAC valve requires resetting .
First locate the IAC valve located on the side of the throttle body and has 4 wires going to it .Procedure is as follows
Ignition key on ,unplug the IAC ,turn key off ,reconnect the IAC .do this 3-4 times .restart the car and hold the rpm at 2000 rpm and slowly lower until it idles by it self .
