also i have those codes p0755 p0433 p1451 p1747 p0743 p0135

 

OK you can check out www.odb-codes.com/trouble_codes/ for many codes and do www.ask.com and type in code numbers for meanings. You have written down your code numbers. Use your scan tool and scroll to Viewing Freeze frame data and also Retrieving I/M Readiness Status. These tools may further help you. Once you have done these things having written down the answers Erase your Diagnostic Trouble codes and reset. Start and run for some time allowing the puter to go thru all its diagnostics. It will take some time for all the Emission stuff to get turned back on as it went into the reset mode and gradually turns them back on. Then read your DTC's again. You might be ok. Other thought is the trailer hitch electrical package may be damaged internally affecting circuits. You may need to unhook it in the wiring. Check the other out first. Your codes refer to ( shift sol B malf. p0755) - ( heated Catalyst efficiency below threshold Bank B -p0433.) ( Evap Control System Vent Solenoid -p1451). ( p1747 trans code PSI control solenoid short circuit seek pro help.) ( po743 Torque Convertor clutch solenoid circuit) and ( p0135-O2 Sensor Failure Bank 1). Most of these may reset with erase and restart and warm up learning cycles. If you have trailer/tow package with trailer brake package you may have Ford Trouble if the brake was in operation. (The Catalytic Converter may be plugged on B Bank.) Causing your rough running engine situation.
