Rough Idle/start when engine heats up. 200 1993

Can anyone shed some light on this problem?
Car starts normally on first start of the day and drives with no problems. After a few miles and stops, each start gets progressively harder and idles rough to the point that it will stall coming to a stop or surge several times and then smooth out. at it's worst it will start and idel rough until it shuts down. It all seems to get progressively worse as it gets hotter. After a few hours/over night of cooling it will start again with no problems.

I have checked the diagnostics and it has no codes.
Can the speed sensor be causing the problem? I did notice the black shielding on the wire is missing at the bend before the plug at the firewall.

Any help will be appreciated.
