when i go to start the car in the morning, after it has been sitting all night, it will start up but then die out or it will idle really low and rev itself up. it seems like it is ididling low too after i am driving (like 500-600 rpms). when i press on the gas really lightly it will feel stumbly and sound and feel like it is missing or something. i had it checked for codes and we got a 44 which i was told means a lean exhaust. do u think that has anything to do with the way it is running. what should i look into fixing. fuel filter?02 sensor? IAC,TPS? or is there like a huge leak somewhere? i already have done everything in the sig so i have ruled igniton out. please help.

I had this similar problem... Try looking for any vacume leak, clean your IAC with carburator cleaner. If this does not solve your problem, Check your O2 sensor if it is carboned up then try replacing it. Mostlikely it could be your O2 sensor...

I had a similar problem to. My solution was that the Idle needed adjusted with the Throttle stop screw.
That was a tremporary fix what ended up happening was the IAC was open too far and was not adjust properly. When it finaly failed I had to put a new one in. Did the reset procedure for adjusting Idle and what not. then Adjusted the TPS to the proper readings and ran perfectly afterward.
