Low idle on Supra

[Dim Sum]

I was wondering what is the correct rpm when starting up? to my knowledge it should be just over 1,500 and just under 2,000? then it should drop once engine warms up.

 

I started the Supra up today after driving it last night and it was idling around 1,000 and slowing dropping,and dropped to roughly around 500. Its sounds fine and tick over perfectly when driving. While its been on the road for a little bit i noticed it when to sit at 1,000rpm whenever i stopped, but surly that seems low right?

 

I found this http://www.mkivsupra.net/vbb/showthread.php?210956-How-To-Clean-Idle-Control-Valve-Cleaning-Aka-ICV-(IAC)

 

Would this be the only solution or is there something else at play ?

 

 

Spec is a 6Speed TT BPU

500 seems a little bit low, yeah. I always thought it was circa 900 they're supposed to idle at?

i thought it was around 600 idle when warm

From what I read on the 'what to check when buying' guide in the faqs section it should go down to around 700?

So am i over reacting

 

Any more advice would be great. I could always upload a video tomorrow, just to make sure its all fine.

I always thought 700-900 was average, 500 seems to low and would feel like it'd stall?

 

 

Have you changed our oil recently? A friends supra idled really low when he was really low on oil :/

Okay update:

 

The supra is fine now, I have no idea why its fine.

Didn't drive it for a day, took it out the next day it drove fine. Idle is around 900, hope this issue don't come back with a vengeance lol.

 

I've had a service on the Supra recently so it wouldn't be the oil, but for the sake of it i did check. Engine oil is all good.
