Idle too low

Do you think the dealership can turn my idle up? The truck idles at 500rpms which is too low IMO b/c I can feel the engine vibration in the cab of the truck. I've always considered this a characteristic of a cheaper low budget econo type of vehicle. I rented this POS Chrysler 200 once and you could feel and hear the thing rattling from the low idle and it only had 20,000 miles on it.

 

Idle is set by the ECU tune. The dealership cannot change that. If it is indeed low, you may have another issue. You might take it in and have it looked at.

 

My truck idles just above 500 at running temp, as long as the AC is not on. Doesn't bother me, seems pretty smooth

 

Another thing, since you have a 19, you need to let it break in. The engine will get smoother with miles on it. Mine had some idle issues as well. Now at 7K, things are much better and mileage is improved.

 

Idle low ? Vacuum leak?

 

I second letting the engine break in with mileage. All the metal is mating and honing itself. When I got mine new from dealer at 8 miles it would misfire at idle and have low rpm etc. I now have 18k miles and have been running 89 octane (midgrade) California gas. since about 2k miles Perfectly smooth idle not a hiccup ever since.

 

Thanks for the advice....I just passed 3,000 miles today and yes my gas mileage isn't great at all either.

 

What engine? What is your actual mpg? Any mods?

 

The V6...my avg mpg has recently creapt up to 17.6....my F150 was getting 16.8 with a 5.4V8 a leveling kit and 34 in tires so I hope my mpg on the Tacoma starts getting better soon

 

Interesting, I have the V6 too.

 

It won't get better unless you start driving differently

 

I love it when people think that the MPG estimates printed on every window sticker applies to their driving style while remaining completely ignorant of the type of testing that went into the estimate in the first place.
