Question about 1994 Jeep Wrangler
No power in high gears
Its a wrangler ? right?
why not scan it the CEL glows for smog reasons.
we ignore the that silly light and scan it. for truth.
the ECU on this car , you need to use the keyon off trick to get the flash codes, (i have a obd1 scan tool that works, but costs $200)
low engine power, tranny not slipping, (m/t or a/t?) in order .
bad fueling can be, fuel pressure low. or bad inputs to ECU
or leaking or clogged injectors. (lots of test here, )
there are simple tests for each, all part of what we call , doing basics.
what to guess, or tests.
there are only 2 choices. (besides TAKE IT IN)

I would start with a test drive with a fuel pressure gauge on it make sure you have spec. 35 - 40 psi. Clear codes and record all the freeze frame data in obd2 as you will need this in the diag process. 442 and 456 are evap codes I believe, do they return with the 300 misfire codes? Either way you need to reproduce the problem with the gauge on it and get the first code it sets. Could be fuel pump/filter/sending unit assy. In this case you will need to pay attention to the fuel level when this occurs. (same level as before)

Sounds like you have a vacuum leak for the lean code and the misfires. I don't see a 473 code in my manual, but have a 463. The 463 is for the fuel level sensor open or voltage high.
