Fault Codes and Problems

Hi I have a couple of problems I would appreciate advice on.
I started going offroading with my ZJ a couple of months ago and that is all I use her for these days. Sometimes she is parked up for a week or two but starts first time and runs well.
1st problem.
About 2 weeks ago I got a misfire on her but it cleared up after maybe 30 -40 seconds. Did not come back for a few weeks and then same again, misfire , hesitation 20-30 secs and then it clears itself up. Not had the misfire for maybe a month and tonight when driving home from the offroad sight misfire came back again and again clears itself after 30-40 seconds.
2nd Problem
When I have driven to the offroad sight, 15 miles from where I live it will never switch from hi to lo range straight away, I sometimes have to park up for 20 minutes to allow her to cool down before it will go into lo range. When I am at home and the ZJ is cold it will switch from hi to lo straight away.
I checked for fault codes and got back the following

P0743: Torque Converter Clutch Circuit Electrical
P0753: Shift Solenoid "A" Electrical
P0138: O2 Sensor Circuit High Voltage (Bank 1 Sensor 2)
P1765: [BMW] CAN Throttle Valve
[Mazda] Transmission 3-2 Timing Solenoid Valve
[Mitsubishi] Crank angle sensor open
[Seat/Audi/Volkswagen] Hydraulic Pressure Sensor 2 adaptation at limit
Pending Fault Log
ECU reports no pending faults
Historic Fault Log
ECU reports no historic faults
Other discovered fault codes
(possibly pending, current or manufacturer specific)
ECU reports no other fault codes logged
End of report.
Could anyone tell me if the reported codes have a connection to the problems I am having?
