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

[MtTrails]

nice tool, one of the very best in the cheap, category, (an Innova is about $160)
i have one, the older version, this one is a good china model, much improved, can plot live 02 readings graph mode, nice.

how old is front 02,
if original, it cant be good. not now.

the sensor is on front of cat, side.
B1S1 means bank1 sensor 1, 4 banger has 1 bank and S1 is on the tail end of the exhaust header,called front 02
leave the rear of cat sensor alone, waste money to touch it, until p0421 happen and smog man nasty

i see your tool has review data button,nice.

Even reads, records and plays back live sensor data !!!!
can display Freeze Frame data
and pending codes as well

looks good
and will plot 02, says so... like mine does. older.
do not flash up grade this tool, unless the maker ask you to...seen many do this and kill the tool dead.


that is a lot of bang for the buck.

good luck

Is this the sensor I need?
