2000 gmc seirra will start fine first start of the day but idle rough and act like its going to die. Then it will come out of it and do it again. Any ideas?
Have the Throttle Body and the Idle Air Control Valve cleaned. Check air filter.
Where would the idle air control valve be?
Google your question with year , make, model and it will show you were and how to clean.
Thank u. Hope it works
