TOYOTA maker.
Toyota Land Cruiser Prado<<<<<
this car?
Gen 3 Cruiser. with 4 petrol
engines then.
no country told and is not USA car. we know that, but where? first sold
or VIN/
no engine told v6 size? 3.4 or 4.0L V6????????
wiki says the
3RZ-FE engine<<<< this?.for 2004
my guess ,is huge
vacuum leaks.from lots of hoses even brake booster Vac leaks or hose never connected first.
IAC stuck open
TV stuck open on TB or gunked open
cutting out means stalling or just spark misfiring/?
getting too much fuel ,proved how? just RPM???????
the engine uses AIR, and this are he EFI adds fuel to mach air. mass.
that is how EFI works (be it mAF or MAP based)
online searching snows MAF sensor part of the TB.
some cars have idle only mAP sensor, but we have no books on this enigine.
let me explain MAF. mass air flow sensors
it measures ever microgram of air sucked in to the engine
the MAF tells the PCM this and PCM injects on mass air flow measured.
if you have any kind of vacuum leak the engine goes lean and slows DOWN LEAN BUT NOT IN COLD ENGINE STARTUP ENRICH MODE.
but not all engines witH MAF, SOME HAVE AND IDLE ONLY MAP SENSOR THAT IF VACUUM LEAKS HAPPEN THE ENGINE SCREAMS
KNOWING these to things, vacuum leaks
or in the MAF world UNMETerED air flow leaks.must be repaired.
all vacuum leaks are bad. besides, IAC allowed.
