have you tried changing the fuel filter?
it could definitely be a defective injector or low fuel output at the injectors.
it could definitely also be a vacuum leak at the throttle body, intake manifold or any of the vacuum hoses
ignition timing may be off
engine emission control system may have a fault
cylinder compression may be low or uneven
ignition system may be weak or faulty including glow plug(s)
camshaft lobes or valve train components may be worn

The OBD II code for P0400 is Exhaust Gas Recirculation Flow Malfunction.
I'm sure the only thing you have left is you may have to replace the EGR valve or check for any leak from the vaccum lines going to to EGR valve.

hey there i cant tell you what you are missing but i can tell you how to disengage the front wheels . ok you have a vacum line that runs right under the battery and a line that comes up from the front diff. to the same place ( you may have to remove batt and batt tray to get full access to this) un bolt it and temporaly put batt and batt tray back in start it up and decompress this and see if it comes out .... you should here clunking noise if it goes back in ... if thats the case just pull that big vaccum line off .... to test get all four tires off the ground and have some one put it in drive but dont hit the gas it should turn on its own ...if that dont work check the cable that runs down to the differental

Have dealer check the computer codes - I had same problem and it required that the accelerator module be replaced - this is "drive by wire" system - no direct hookup to the throttle body.
