Hello

I have a 94 4Runner 3.0. Has only happened twice, doesn’t happen often. I get very low idle. For example today, I was at a red light and the RPM was almost at zero. First time I was under 500rpm. But it normalizes afterwards. Check engine comes and goes, but today I tested it. I think it’s code 25 lean fuel air mixture. I took it to a shop previously for a high idle issue, it was a vacuum leak and it worked fine. Now I’m having low idle issues that comes and goes. Please see video attached ! Any tips please shoot!

 

still a vacuum leak?

idle air control defective ?

 

well that’s what I’m asking , what do u guys suggest to check. I had a high idle issue weeks ago, there was a leak and the shop fixed it. I really doubt another vacuum leak tbh.
