The reason that the engine will run fine when it's cold is cause the ECU is in open loop, when the o2 sensors and the coolant temp sensor get to the recomended min to go into closed loop thats when the ECU takes over. Anthing before that the ECU is running of fixed/preprogramed setting's. I do however find it hard to believe the a FORD shop cannot retrieve a trouble code, those things will come on for just about anything, eaven a loose gas cap! I would gestamate from not having seen the car that it's posiably an input sensor that has failed. The dash lights coming on has me wondering about the charging system though. Well Im sure it can be fixed, let us know what was wrong.
