Idle low

[yariseggvvti]

When I come to complete stop, My idle is low and vehicle is shake a bit.

Then I shift in to neutral, the vehicle is okay.

Air flow meter problem or something else?

I replace it about 20k ago.

Any idea and appreciated advice!

Try cleaning the throttle body.

Seafoam it, or take it apart and clean it.

does seafoam really a help or just a myth?

[Betrivent]

Seafoam is effectively a strong solvent, which at the very least, will take some grime out of the engine.

becareful cleaning the throttle body!!! i did the same thing and...wallllaa!!!! 500 euros of damge!!! i was too idiot to use wd-40 to cleaning it. results--- damaged afm and throttle position sensor.....changed them. car it is ok few few weeks, but later i experienced high idle!!!! i checked on internet. found out to clean my idle control valve....i used throotle cleaner....result was epic!!! more high idle about 4000 rpm!!!!! 250 euros on idle control valve - 90 for afm - and 70 euros on tps......plus mechanic labour. ct scott told me to NOT USE wd 40 or something similar in this sensors. he was right!!! i know a friend who damaged the alternator with wd 40 u similar too! becareful with these solvents, sorry for typing too long about this, but i dont want some people to pass this shit experience like me. after all, still i got little rough idle...but it drives perfect!! (note all sensors are from original toyota parts)

Even though the difference doesn't seem to jive re time zone difference (which I've found isn't always accurate on Yarisworld), I have a feeling that in real time yariseggvvti's post = only 5 minutes after CTScott's, so he was likely typing his post when CTScott posted.

of cos not, the time is reflected differently on each account, but the time system is always constant. He posted 14 hrs afterwards.

PS: don't go off topic

should have followed instructions on here or micro image... or at least find more info on the internet first before attempting this. Only TB cleaner is to be used to clean TB, although carb cleaner also works but some say it damages gasket.

You're right, I missed the AM/PM difference. The rest of that assertion, maybe (not really worth more analysis as the AM/PM miss makes me wrong anyway). He should have noticed CTScott's post, but I think he just posted without 'catching up' re reading the thread. I don't think he meant any disrespect to CTScott (and I'm not saying you think he did). Also, my post wasn't any more off topic than your question mark.

what the heck? find better things to do in your life than analyzing this. I am not responding to you anymore.

You've gone off topic again.
