2005 Tacoma 4 cyl. high idle question

My 2005 Tacoma (4cyl.)idles at 2200 rpm on 1st start (when cold). This
seems way too high to me--anybody else have this? thanx in advance!

Let me describe it to you: (depending on how cool your region is as well as
the season) you start it and it idles high for 2-5 mins, then idles down to
a 'normal' level unless you've got the defrost on - which will cause the
engine to periodically 'surge/rev' systematically.

Sound familiar? Yours sounds normal unless I've missed something.

Stew-thanx for reply! Yeah it idle's back down as it should-It just
seems like the high idle setting at startup is excessive -of course
I'm used to my old also--Ha! Thanx!

I think it's normal, mine does it too. I seem to remember reading
something about a fresh air pump that runs for 90 seconds after a cold
start.

I'm guessing it's something to do with emissions requirements and the
rich fuel mixture needed for a cold engine start.

My '05 4.0L Tacoma and my 4 cylinder '01 Subaru Outback do exactly the
same thing. My neighbor's Hemi Ram sounds as if it also starts like this.

I'll let it run for 10-15 seconds, tap the gas pedal, which drops the
RPM's, depress the clutch, and slide it into gear.

If you didn't touch a thing, both will automatically drop the RPM's as
the engine starts to warm up.

Does the manual mention high or cold idle?

Thanx for the replys everybody! Barry, the manual doesn't say anything
about the high idle (that I can find anyway). It is probably normal--it
just bothers me that the engine would rev that high when it's cold and
no oil pressure. It comes back down to normal shortly. Hope this one is
a good as my last one (87 22r--271,000 miles and still running). Thanx
again guys

I don't drive my Taco to work, so I couldn't check myself.

I had an '85 do 300k. I've got the same hope!

My 2005 Tacoma does the same thing. I did ask the dealer and they said it is
normal. They also said nothing could be done about it because it is
controlled by the computer chip. - Bob
