warm starting problem

Thank you moderators for assisting us.

98 Chevy Lumina 6 cyl 3.1 L. 148K miles: When the engine is warm, I have to keep the gas pedal slightly pressed to get the engine started. Because of this, I am dreadful of running short errands to neighborhood stores. OBD II code reader shows no error code. Just an old car problem? But is there a fix? Thank you for your help in advance.

I will spray clean throttle body and IAC motor (don't quite know what this looks like but I have a shop manual at home). One followup question: I have problem only when starting warm. Once started, idling is no problem like at traffic light, etc. Should I still suspect TPS as one of the culprits?

By the way, do I need a special gauge to check TPS? As far as I remember, it is about $50 part and would rather replace it than buying an instrument to check it. Please advise. Thank you.
