This may be too long an entry, do not want to upset anyone here at Ford-Rangers.com.
First (after cutting off the frame and putting a new rear section on from about 3 inches past the cab corners)
I have a stick on the collum that shows the typical 1  2 and  D with a circle around it. 3 speed with overdrive...(which by the way does not work. I think it is stuck in OD)  HOWEVER, the truck shifts 4 times.. that to me is 5 gears.. ??4 speed with overdrive??

Oh btw it is 4wheel drive.. electric switch on dash. Fearful to try it.

Driving along, if you hit a bank steep enough to cause it to want to downshift.. it spits, sputters, coughs and sometimes bucks like an angry muel. Someone (grr) said it was the Mass Air flow sensor.. so we now have a new one. 
 I borrowed an OBD II scanner.  Throttle Position Sensor was showing high, and Throttle/Pedal Position Sensoer was high as well
$ 50 dollars later, new TPS changed both errors.. throttle and throttle/pedal. However the bank 1 and bank 2 still showed lean.

After the new exhaust, the bank 1 and 2 lean went, and P0136 and 141 decided to shout out.. O2 sensor blah blah blah.
The exhaust shop did not put on those two  canisters- I think they were catalictic converters....
OH and he said a partially stopped up fuel filter was the cause of the lean errors.

I went to the "live" thing on the scanner. Here is what showed up
DTCFRZF Po 171 (which we already knew) 
Fuel Sys 1 ---  clr

Fuel sys 2 --- N/A
Load PCT % --- 37.3


"ETC  Fº --- 205

Shrt FT1 %---18


Long FT1 % 25


Shrt FT2 % --- 11.7


Long FT2 % --- 25


RPM (which the rpm gauge does not work) ---1484


USS MPH --- 21


If ANYONE understands that gibberish and knows how to fix me .. what is it called.. drive train??  I would greatly appreciate the help.


Cheers
Sammy

These numbers mean your truck is running like absolute garbage:


Shrt FT1 %---18


Long FT1 % 25


Shrt FT2 % --- 11.7


Long FT2 % --- 25



Mine run at like -3 to +3 for Short term fuel trims and damn near 0 for long term.


Anything less than -15 or positive 15 for a set time sets a code. Because they are all positive you are running extremely lean. That looks like extreme vacuum leak to me.


BTW that extra gear you feel is the torque converter locking up at highway speeds.

I don't think I have seen the long term fuel trim that high. Ever. You poor guy!

As far as fixing, one thing at a time.

If it is a vacuum leak it could be as easy as the hose to the power brakes and as deep as intake manifold gasket. If it will stay running you need to listen under the hood, I use a poor mans stethoscope.. a piece of small hose in my ear placing the other end at spots I suspect there might be leaks. Too bad you don't live up the street I'd come by and take a look.

Oh, you have a long way to go before you can post longer than James (Undrstm8ed)! LOL  Honestly, type as much as necessary to convey any pertinent information... the more we know about the vehicle and the problem, the better we can help you.

As for engine stuff, I will bow out as my expertise is severely lacking in that department.
