600 rpm idle but...

... it sounds great. No stutter. No shake. Nothing. Is it still a problem?

no. just raise it up a bit if you like. Probably will have a smoother take off from idle if ya do. If you have smog tests there you need to have it at spec. (800)

Bad advice.

It can cause problems in the long run through excessive wear. Main reason being that your really "lugging" the engine when you start pulling at 600 rpm. Oil pressure isn't going to be built up enough to ensure minimal wear occurs under load. Any manufacturer will tell you to NEVER operate your engine below the factory set idle speed. That's the minimum "safe" speed for that particular engine.

just my 0.02 cents

The thing is you need a timing light to get everything to factory specs. I always do my by ear.

How do you figure that?? We are talking a difference of 200 rpm. That will not lug your engine that bad and you oil pressure sure won't be lower enough to do any damage

Well, I didn't figure it at all, the engine designers at Toyota did. It's actually considered common knowledge by any mechanic I know. Curious where you've come up with the notion myself. It's auto shop 101 type stuff really, totally applies to ALL engines. Not a debatable issue at all, a mechanical certainty rather.

Don't you think there's got to be something to the fact that you don't see a range of idle speeds listed for an engine? For example, it doesn't say "3VZE Idle Speed:600-800rpm" does it? Wonder why? Like I said, OIL PRESSURE! I mean why not 400 rpm then or 200? Trust me there's a reason, and that's it.

You have BARELY enough at idle speed to handle ANY loading of the engine safely. NOT enough for operation under which, engine pulling a load or not. Anybody who knows ANYTHING about internal combustion engines can tell you this.

Ask if you don't believe me!

Find me ONE instance where it's stated otherwise. (Don't hurt yourself tryin', it's not worth it.)

Give me oil pressure readings at 600 rpm and at 800 rpm then we can talk

Hmm, very interesting, my 22re idle is about 600ish, I'll bump it up tomorrow. Mudhippy, your (or rather, Toyota's) reasoning is quite sound, though I wonder is 100rpm really makes a difference. Not debating this, just wondering.

Trust me...as someone who has been in the business with toyotas for the last 10 years. It doesn't make a difference

Hmmm... Explains why my oil pressure gauge is always right down at the low end till i really get going. Thanks! Saves me having to start another thread!

Now... I'm really sorry sorry 'bout this one, buuuttttt... How does one go about adjusting idle?

Search for "idle adjustment screw". I have a 22RE, but the logical place for the screw would be on top of the throttle body near the attachement point for the throttle cable.

Sweet. Thanks very much for the response. I realize it was a pretty elementary question for most people to even reply to, so I do appreciate it.

My V6 idles smooth at 700rpm so I wouldn't figure 600rpm would be a bigf diff even on the two different engines.

If you say so, but I'm sticking with the FSM on this one.

You REALLY need to read this thread https://www.yotatech.com/forums/f116...-motor-126208/

See what others on here say about it.

Shouldn't be too hard to adjust your idle up a little bit. Yer not too far off from stock, I believe it's somewhere near 800RPM, If you're worried about it that much, consult your certified Toyota counselor if you need someone to talk to about it.

What? Dude this is a place where people can come to get accurate information. From "techs" or not. Don't even think for half a second that you can go around spouting personal opinions and calling them facts without being challenged on it. If you don't have any way to back up what your saying, keep it to yourself.

By the way who gave your word the authority over the Toyota Factory Service Manual? You think you "know better" huh!?

Bulldada. Ain't nobody here gonna take your word for it on anything just because your a self-proclaimed "toytech".(AS IF!)

P.S., what happened? Couldn't find a darn thing to prove your theory there could ya? So you just wanna play "smart guy" with me instead? You may want to quit while your ahead then, because the longer this is drawing out the worse you're looking. Comeback? Catch up first.
