Cold Start Warm-Up Time

Morning All,

1st time Tacoma owner and new to any real threads, so I'll start with what seems to be the norm; went big with the 4DR Limited 4WD Auto, currently with 160 miles on it.

Something I've noticed is that... the damn thing HATES to warm up. I'll sit in the truck for 2 or 3 minutes and the idle stays around 1,200 - 1,300 RPM's. As an experiment, I started it and let it sit for 8 minutes; only went down to about 1,000 RPM's. Should also note that the truck sits in a (non-heated) garage that's been around 50° since the day I bought it.

After I drive and get to my destination, the idle sits at a more normal 700'ish RPM's. But. When I get back in and start it after just about 10 minutes or so, right back up to 1,000+!

I stopped by the dealership and they shrugged their shoulders, siting that they've only sold about 5 3rd Gens and they really don't know much about the truck yet. Also stated to let it break in more to see if the computers just need to learn a little longer...

Anyone else noticed this issue, or is it just me?

 

thats just normal for the tacoma. My 2nd gen does the same thing. I wouldnt worry about it, now if you were idleing above 2k then youd have something to worry about.

 

Started my truck yesterday morning in 20 degree temps. Proceeded to drive it like every vehicle I've owned and it got me to my destination. Don't see an issue.

 

Emissions require that engine and catalysts get to operating temps as fast as possible. High idle is just the ECMs programming to warm it up as fast as it can

 

not trying to be mean but going into a dealership and asking that is equivelent to going into a dealership and saying," theres a problem with my car, when i put the shifter in d, it moves forward and when i put it in r it moves backwards"...they are going to stare at you with a blank confused face not knowing how to answer you right away.

I've only ever owned japanese vehicles but all the ones I've purchased, none of them warmed up in 2-3 minutes from cold soak. if its 50 degrees outside, ill let it run for at least 10 minutes before i start driving for all my cars/truck.

sounds like you need a remote start, i always try to let my truck run for like 5-10 minutes before driving. if its extremely hot or cold, ill let it run for 20-30 minutes before driving.

 

at 50 degrees you don't need to let it run for 10 minutes before you drive. You can start it and drive. All you are doing is wasting fuel.

 

Mean? That's funny as hell!! I used to have a 13 Nissan Rogue, and it was ready to go in about 3 or 4 minutes; this is just a bit of a change for me. Always sounds angry when I put it in drive when she's still at 1,000 RPM's.

And thanks to the rest of you for replying; looks like this is just something I'll need to get used to!

 

I don't let my truck hit 4-5 k rpms without it being at optimum temp. I'm always getting on my truck.

And I'm not worried about fuel. My civic si gets 15 mpg during winter and 19 during the summer,(16 during summer if it's extremly hot that week ). If I'm ok with that. I Should be ok with truck. Though, I haven't calculated my mpg on the truck yet.

 

and make sure you hold that brake before putting to gear because the RPM's do not drop.

 

My '14 does the same thing. My '03 Silverado idled down to normal rpm's almost immediately, even on cold starts. So now, with the Taco, I've learned to be a little more "patient", and let it idle down "close to normal" before I drive away.

 

My 13 does this too. I'd say it's normal.

 

Having to warm your engine is an old wise tale. The worst thing you can do is let the engine idle, it's in the owners manual and has been in about very vehicle since the 80's. You are better off to just drive slow and easy for a few blocks to warm it up.
it idles faster when cold because the timing is changed to aid in starting and warm-up. It works a little different in every car, but is normal. Most of them will go back to regular idle when you start driving or tap the peddle.

 

No they don't!! Mine actually raises in RPM's a bit before it drops back down.
