Are you getting a check engine light? Have you changed the air filter lately? Sometimes a vacuum hose can get pulled out when removing the filter--check that. For it to happen suddenly--go back to the last thing that was done.
Thanks for the quick reply. I did nothing, no air filter replaced. I noticed the vehicle vibrating at idle speed last week but yesterday it stalled first time while on idle speed at a traffic light. I put fuel injector cleaner in gas tank to see to if idle speed comes back to normal. Sometimes it works. My vehicle is standard RAV4 2006 2.4L 4-cylinder.
I have a 2007 i4 awd.
changed the battery the other day.. it was without power for about 15mins while i swapped it..
when i started it afterwords.. it was idling like it wanted to stall.. really low below 500rpm.. so i turned the AC off and
drove it around for about a day or so and she is all better now.. even with the AC on.
I chalked it up to the ECM relearning.
Honestly I dont know why it did that or why it stopped. Any electrical problems?
