98 Escort Hard starting when hot

sounds like a dodgy mis reading of a sensor caused by electrical resistance which is turning choke on and flooding engine.know the fault but without car in front of me its difficult to diagnose,could be auto choke sensor which is on right hand side of cylinder head ,but not sure.best is probally dealer have you tried spark plug gaps ??25th although this would cause problems with cold starting not hot starting but its worth a look
