97 Sidekick Sport 1.8L - CUTS OUT AT 1/4 THROTTLE

[fixkick]

the inside cable (kickdown)is bathed in ATF oil full time, sits, just above valve body
yes the lower end can break off, and then the cable inside wire, pulls out of casing. see part ID 20?
the cables can crack out side casing is plastic, and if did, water gets inside cable and that is all pure steel there, RUST it will

505, means PCM has trouble controlling idle. (means iSC valve, seems to not respond correctly and hold idle at 800rpm)
any thing that cause idle controls to fails sets this DTC. even leaking, EGR,lean engine, misfiring, or sticking ISC.

that shaft through the transmission is long, and is called the manual control vavle shaft.
left side shifts there.
right is PRNDL switch see that bundle of wires?
the kick down is behind that PRNDL.

see that bell crank device, #20 (in a vast flood of ATF fluid,there ,like shower of aTF, as the planetary gears fling oil madly.)
see that hole there. the cable fits there, in that hold, just like the other end , a ball end on cable fits in that hole
see spring 17 , that is what keeps the cable tight, (acceleration,) other wise it go slack
cables,(all) have many failure modes, rust or break, either end.
