hey guys

installed the K&N sri setup , as per the book , but car ideling very low and eventually cuts out , what is the porblem ?? all pipes are on and working

YAR1S · 12-17-2009, 03:19 PM

the air sensor(I think thats what its called?) attached?

aucorium · 12-17-2009, 03:47 PM

yeah , air sensor AKA mass airflow meter is on.

aucorium · 12-17-2009, 03:49 PM

everything is on and plugged in as per instructions , im not sure of the air sensor is maybe faulty ? or if the vacume switch can cause the car to idle so low ?

come to think of it , with the OEM intake on the car did occilate quite hectically at times , like irregular ideling ,mmm , wonder what it can be ? maybe the intake made it more promenant

*Astroman* · 12-17-2009, 03:57 PM

did you unplug the negative terminal completely for at least 15 minutes? When I installed my AEM I just unhooked the battery during the install and I was fine.

aucorium · 12-17-2009, 04:02 PM

yeah , i unplugged the terminal while installing , then reconnected when done , was off for approx 50min

*Astroman* · 12-17-2009, 04:06 PM

Any chance the MAS was damaged? Any check engine lights?

aucorium · 12-17-2009, 04:08 PM

can the idle be set on the yaris ? maybe the dealer can set it with the ODB2 port tester ?

i took the MAS out agian and checked , didnt see any damage , no engine check lights. scangauge also didnt pick anything up.

*Astroman* · 12-17-2009, 04:10 PM

Honestly I don't know but if I had to guess I'd say no as this is something the ecu probably handles... But go ahead and correct me if I'm wrong.

aucorium · 12-17-2009, 04:10 PM

i wonder if alot of driving will sort it out? idling is very low , approx 400rpm - 500rpm

Thirty-Nine · 12-17-2009, 04:19 PM

Strange. I just installed this unit without a problem. I wish I had something else to add ...

cali yaris · 12-17-2009, 04:34 PM

Idle is not adjustable. It does sound like a MAF problem.

My Yaris always rpm hunted, I never liked that about it.

aucorium · 12-17-2009, 04:41 PM

yeah , could be MAF , i wonder if it isnt mabye dirty or somthing ? i did notice a little bit of black dirt on it , gave it a little wipe , but not properly. is a MAF very sensitive or a little robust ? how can you clean a MAF ?

chongopants · 12-17-2009, 04:43 PM

try resetting ecu and cleaning maf

aucorium · 12-17-2009, 04:48 PM

already reset ECU , but havent cleaned the MAF , i did notice some black dirt on the one side of the sensor , how do i clean that off ? dont wanna break it

aucorium · 12-17-2009, 04:56 PM

i noticed in the K&N sri setup there is a small oval shaped piece of metal at an angle in the intake , why is it there ? to create wind turbulence ?

PHXDEMON · 12-17-2009, 09:59 PM

Now by cuts out do you mean the engine stalls completely? If it just oscillates a little on idle that is normal if you have an intake.
