[Ryan_2.4litereater]

ok. so every once n again when im driving ill be coming to a stop light and ill push in the clutch and brake to stop. well when i push in the clutch, the rpms will go down to normal idle level, then almost immediatley after, the car will start to bog out. the rpms fluctuate down wards. sumtimes my car will cut off, then ill just turn it on again.

now this only will happen every now and then. its wierd bad fuel injectors? i have no clue wut to look for. sum one help me

you have to check the iacv aac (intake aux control valve) or aux air control valve this valve control de idle rpms..

[Ryan_2.4litereater]

how do you do that. wheres it at???

[johnnyballs180]

on my sr20, the iacv (idle air control valve) is on the driver side (passenger in the states) of the motor. it should be hidden behind the intake, in an impossibly retarded, hard-to-get-to place.here's a pic of what it looks like:

my o2 sensor is bad and my car's running a little rich and unsteady.

good luck!

oh, and for trouble-shooting the o2 sensor, there's some threads somewhere on nico that can help.

willing to bet its a problem with the coolant temp sensor itself or just the connection.

[Ryan_2.4litereater]

how do you fix that???

why the coolant temp sensor?

[grecco28]

ok, some times the failure of coolant tem sensor can do that kind of failure but the first step is check if theres some dtc stored in the ecu..

[grecco28]

check the inyector resistance it must ben in 12 to 15 range max...
