Default Bad idle after long drive

drove from OH to NC, now when ever my car is warming up, it idles very rough, smells like gas, and intake makes chugging sounds

once it warms up to about 170-175 F it it will go away and then everything is fine

i thought it was something with the coils, but after swaping to a different set, it works the same way
Any thoughts on what else it could be other then a MS setting?

only thing i changed was VE settings tung for gas mileage, and that was about it, im trying to rule out the MS being any part in it

+1 on heatsoak...probably clt sensor or something doesn't work well until it heatsoaks and it works again

tune your CLT Based air density table....turn it to AIT under advanced, and add fuel as the temps increase.
