If your 2005 Ford Escape is running OK now the next step would be to have all the fault codes cleared from the engine control computer. After the codes are cleared watch for any new driveability concerns and keep any eye on the check engine light. If the engine begins to run poorly again or the check engine light comes back on you should check the codes again to see what code(s) have set, diagnose the code(s) and repair accordingly.
