yaris stall at idle only when its warm
Have 2010 yaris manual, car idles rough when comes to stop and than stalls. only happens when its been driving for a while (1hr or so) , when the car is really warm. (the stall is random..)
No MIL lights, checked for vacuum leaks , cleaned maf sensor checked for voltage, checked a/f sensor and oxygen sensors , around averaging o.5 . Checked for stfm and ltfm seems fine.
checked injectors for ohms all similar.
Has anyone experience this symptom with their yaris. it is driving me nuts.
I dont have a smoke machine to check for leaks, but the problem only happens when the car is really warm, sounds like it wont be a leak problem, most likely would be a sensor somewhere..
thanks advance for your reponse and help.
