High Idle when hot - low power on up hill

[fixkick]

Hello
So I looked at the cables of the connectors...
At the OBD2 connector I have only pins number 9, 16, 5... So it seems that is is not real OBD2
some 1997 countries have OBD2 but you must use, and adapter.
need colors of wire to do that
16 must be 12vdc power. key on?
5 must be black ground and 5 is ground on all obd2 systems.
9 would be serial data. what colors are the 3 pins.
some 97 world wide have OBD1.5 )with adapter makes obd2, and flash codes too. a dual system, not seen here.
pin 9 can be ALDL serial, works only with TECH1 or TECH 2 scanners. not home style.

i'd avoid connector 2, (i will study the colors later for you today) brown and gray? ill look up .

The colors of the other 2 connectors - please see the picture:




What I should do now to make the DTC check ?

Do I need to Jumper 2 to 4 pins on connector 1 and see the CEL for the DTC? YES> jump black = ground to yellow-blue (diag) pins and get flash codes.

Or I need to Jumper the pin with black wire to diagonal pin on connector 2 ?

this will work use colors, only to jump. and win.

i think brown is tachometer spark signal, weak.
for using tachometer under hood.
gray not sure, yet
