You don't have all those, as problems,but need to
look at the data

If you have spark plugs that are not in the motor over 3 years
or 60,000 miles, no COP Coil Misfires,clean throttle and MAF,
good air filter,no vacuum leaks,then I would suspect the temp sensor,
and look at when it go into closed loop (O2 Sensors take over fuel regulation)

Is the door ajar light in the cluster illuminated ?

Could be the door ajar switch ( part of the door latch ) is gummed up, and needs to be WD-40 sprayed into it, and close open the doors a few times, and repeat.

The autolock uses the same input, to know to lock the doors when you press the brake pedal while moving.

you shouldent need to flush the engine just make sure you drain it good..10w30 synthetic is fine

Already replied to your other post on the same topic :

Could be a problem with the vac lines to the IWE ( Integrated WheelEnds ), or a problem with the IWE solenoid, or a problem with the ventfrom the IWE.

Start with checking the vac lines, to make sure they are not cracked.
The vac res & IWE solenoid are behind the battery. Here is a diagram of the parts in the IWE vac system

There was a TSB for the 2004-2006 MYs with a bad design IWE solenoid, but this usually was coupled with noise in 2WD.
Start with checking the VAC lines and the vent, next would be to check the IWE solenoid.

at that many miles its do a timing set

possible clogged injectors

If you're using your truck to jump start another dead battery in a different car..your truck should be runing when you do that.....

If you leave your truck turned off and are jump starting another car/truck that way..you are drawing your CCA (cold cranking amps) way down, and really shortening the life of your batery..you'll be needing to get jump started yourslf pretty soon.

Hi,

Try reversing for around 10 yards, then deselect 4WD.

Doing a few snake turns on soft ground may help too if it has wound up the transmission.

If this does not work, it may be a stuck solenoid.
