I have a 1986 Mustang LX 3.8L V6 that gets choked out or flooded I have heard that it could be the EGR valve or TBI or air idler valve, i have also done my own looking and i have 3 catalytic converters 2 on the Y pipe and one a little further down and the pipe gets a little pinched underneath the transmission i was just wondering what you think or if you have any suggestions to gain a little extra more power and stop the choking or flooding

How have you determined that this condition is flooding?

I don't know how to explain it, it's more like choking i guess, because if it's cold and i rev it a little it takes a little bit for the smoke to catch up after i stop and sometimes i will pull of to a stop light and the rpms will drop and and go back up multiple times and when i try to drive it's hesitant and and takes awhile for everything to catch back up

It does sound like an over rich condition but it's going to require a little diagnosis to determine why. One quick thing to check is pull the vacuum line off the fuel pressure regulator and see if there is any fuel inside indicating a ruptured regulator diaphragm.

Do you have any suggestions to why there are 3 catalytic converters? and would it be wise to take them out?

2 of them are pre-cats. That is common on Fords.

Probably impossible to do and against Federal law too.
