Default Fuel Injectors/Sluggish Warm Start

Hi everyone, once again, I am in need of your corvette wisdom lmao. I've had this intermittent issue with my 87 sort of sluggish, flooded sounding startup. Its 100x worse on hot starts and mostly happens when warm but still after sitting all night and starting early morning its not uncommon for it to startup and immediately die first try then start fine the second time. Also, this issue is only while idling, the more throttle i give it the better it acts

I've tested resistance on the injectors I'm getting 16.6 ohms for all, next thought was maybe IAC valve or cleaning the throttle body ?
The MAF relays are new, same with spark plugs. I figure its probably wrong fuel/air ratio in there but honestly out of my element and could really use some advice
