High Idle

I've noticed something that seems a little odd. Obviously, the you start the truck for the first time after sitting and cooling down, or for the first start of the day, the idle is higher until the engine warms up. This is completely normal for ALL cars. However, my new Tacoma will idle high even after going to the for 15 minutes. The engine temperature gauge shows that the engine is almost at running temperature, but the idle stays high for quite a while. Is this normal for these trucks?

 

That is not normal. The first tick mark is about 140F coolant temp, it should be settled into normal idle by then:

 

How high is "high"??

 

Do you have the ac or defroster on?

 

What rpm(s) are we talking about?

 

About 1,000 RPM. The temperature gauge shows just a few ticks below running temperature. It stays at that RPM for a while. Until I put it into gear. What I hate is that it jumps when I put it into gear unless I'm very firmly pressing on the brake.

 

I think my first post was a little unclear. Sorry. I made it sound like after 15 minutes it's still idling high. What I was trying to say is this...I drive to the store, come back out 15 minutes later, start the engine, and even though it hasn't really cooled down, it idles like like I just started it for the first time in a while and the engine has cooled back down. Hope that is more clear.

 

That sounds normal. Mine usually idles high for about 10 seconds then drops.

 

I’ll have to make a video. It idles at about 1,000 rpm for quite a while even though the engine is almost at running temperature. It won’t idle down until I put it in gear. But, because the idle is so high, it “jumps” into gear. I don’t know. Maybe I’m the one who’s high. Lol

 

What you're describing definitely sounds unusual for sure. Have you talked to the dealership yet? I'd start there since it's so new.

 

Yeah, that what I was thinking. Just sucks that the dealership is about 45 minutes away. Or, can I take it to any Toyota dealership?

 

You should be able to take it to any of them. If you have any doubts just call first and see what they say. They should check it out for you.

 

My truck is the same way. Its a bit different than my gen1 tundra, but since the high idle is only for a few seconds than return to normal, i figure it must be that way.

 

I’m getting mixed signals. It could be normal or it could not be normal.

 

I’m working on a video. Stay tuned.

 

Now I think I’m going crazy. I drove it, got it up to operating temperature. Shut it off for 20 minutes. Started it up again and the idle went right to normal. I’ll keep you all posted.

 

Okay, this is kinda what I’m talking about. Maybe it’s normal, but it just seems the idle should drop a bit quicker. I don’t know. Let me know what you think.

How many miles? New engines need to learn themselves.

 

157 miles. Maybe that’s it. It’s still young and has a lot to learn. Lol

 

Yeah that’s really young.
