New TC owner.....first impressions

[Klingon]

I've had my 2013 XLT TC wagon for about 5 days now.  I came from a 2005 F350 Dually Crew cab Lariat longbed w/ literally 3 times the cubic inches of my TC.  That being said, it's been an easy transition.  Just need to remember to apply about 80% less pressure to the brake pedal unless I want to go through the windshield.  

 

I did a bit of research before buying.  Like many said, the 4 speed trans. is a little clunky and dated.  The engine is weak but I expected that and accepted it ahead of time.   The driving experience is that of an early 80's econo-box.....like a Reliant K or any other early American FWD.  I know that doesn't sound very complimentary!!  But, as long as it keeps running I'm a happy man. I got second row seating which was a must have.  Body has a few dings but nothing bigger than a dime . I paid $8500 w/  72,300 on the odo.  No major issues that I can see and I used to be a mechanic (a lifetime ago).  

 

Minor issue:  The dash says there is a door open but there isn't.  The doors also wont lock either w/ the key fob control or manually (I turn the key in the driver's door lock and all the doors click locked....then a half second later they all unlock.  I'm assuming the two issues are related.  Never been in an accident.  All the door close straight and smooth.  Must be a sensor.  Any suggestions.

 

Also has check engine light on.  Auto parts store threw a code scanner (if that's what it's even called) on it and said it had a bad O2 sensor.   Easy fix?  Location?

 

Tire pressure warning light is on and will be until I figure out how to disable it.  It came w/ 215/70's on the back and they aren't XL rated.  Max. psi is 44 which is what I have in them.  I'm not hauling anything more than 120 lbs. of kids so I'm going to run them down and later replace w/ XL rated or maybe even C1 or C5's.  Till the....44 psi. 

 

Definitely louder on the inside than I thought a modern vehicle would be.  I know....it's primarily a utility/work vehicle.  I don't get the impression that anything is wrong.  Just a bit more engine noise and vibration than expected.  Is this par for the course?

 

Any advice about what to look out for on my TC would be appreciated
