yes that is what is called a code reader, it is a very limited device.
yes some cheaper Autells are weak.. have one here weak, just for fun to see just how weak. sold at harbor FRIGHT.
yes, some good tools are $300 , , or $50 dongle, old laptop and run $100 software like mine above.. if old laptops about , free, cost is $150 , the hand held tools good are expensive..
not sure me what to tell any 3rd party, i've no idea if they are ASE certified and have a full load of useful tools in the shop, many are just guessing guys, try this ,try that, and pray.
The EFI systems are complex. (as is actual engine)
That is the why wise shops test the engine first, as EFI can not run a bad engine, or near bad.. EFI can hide weakness sure. in fact very well. (example 1 slipped cam time belt)
all we know is: (useful )
now the short list:
500rpm is dead wrong hot, why. (there is a reason any good ASE knows what to do) (there is a bevy of tests to find why)
O2 dead and TRIM stuck at OL not CL, why? Why is it stuck OPEN LOOP , if at idle stuck there find why first but 500rpm sure can do that )
Oh my golly gee, why not open throttle lever, a tad hit 800rpm , CL NOW? so obvious and 10 seconds work,,, tool in face OBD2..
your 02 is stuck dead OL, at 40mph and that TOO is dead wrong.
using a short list, this done right testing, takes any ASE to the right tests and right causes.. as my wise friend says, fix what you know is wrong now and first..
The car is screaming (EFI) why is it 500 RPM why why why: hot engine. (put bleed screw back where it was sure) then see 500 and hear it scream for help. still.
I bet 2 things wrong, at least.. but hope 1.

- idle is wrong a 500, no one once told why, ? nor did tests to find why, this is text book ASE ways, for sure. (lean, rich, AFR or spark misfiring,
- EGR is not stuck open ,main is new, so will not fail at idle ever,well if vacuum lines not connect wrong, OMG bad. that..
- your only scans (very llimited) shows O2 front is dead, and EGR OBD2 are no good like that (self tests by IT) EGR tests must not be trusted,(obd2) if engine vacuum is wrong..
- idle bleed screw set wrong, making duty cycle wrong.. turn it back to where you found it?
- ISC stuck needs cleaning never me seen one not gunk'ed up at 100k miles,
- New TPS and installer failed to calibrate it ,just threw it on, like on new cars, this car is not new. and idle switch reads wrong 5v at hot idle making #5 ISC now Dead. forever.
- WOT power is ok,, (I guess) making me thing ENGINE IS not bad. but I can not drive your car and feel the 95HP there.
- full scans and logs driving easy the aggressive, logging the all sensor data. not done. All shops know this finds problems and for SURE intermittent.
- vacuum leaks done. Smoke test. hoses not cracked sucking in air.
- exhaust manifold not checked for cracks shields off, for causing 02 death. (so common on this car)
