Help confirm the data of 96 Sidekick Sport 1.8l

It must be in closed loop at idle and ,easy cruise.
so something is very wrong with your EFI.
LT FTRM1 (%) (Long Term Fuel Trim1) -14.8   (this is huge number, means engine runs rich. and EFI must subtract lots of fuel to gain fuel mix right)
why loop the tool, on ) O2S11 (bank 1 sensor one (bank 2 is for V6 engine) you have no V6 engine and no bank 2, so that printout is wrong, calling it Bank 2.
s1 is front (focus on S1)
s2 is rear 02. ok.  forget this.
loop the tool on the front 02 sensor, and set it to graphic mode,

here is real 0-scope (prof scope tek) as you can see a real scope does not miss swings. (the tool is super fast)

Look at this OBD2 STAT (OBD Status) CA, it is something about California?? My car is federal.

at 3000 rpm what is the MAF reading.  ?  hot engine, only tests.




failure to attain closed loop means the ECU (EFI system) is lost.  
it has lost control of fuel mix,  one cause (of many are MAF readings are not correct or 02 Sensor #1 front #1 reads wrong)

the O2 must swing.
other causes, (vacuum leaks, leaking or weaK Injectors, misfire gross.  and exhaust manifold cracks, )

how old is that 02 front sensor.? (they have 100,000+ mile life span if using unleaded fuel)

Thanks. So it all means my ecu stops working???
How can it be?? It could be my tool is not the right one?? The car just runs?
The engine is just 097394.
