Engine & DrivetrainDiscussions about the engine and drivetrain of your vehicle.
This is a discussion thread titled "High Idle?", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
I've been lurking for a couple months and have been checking this site several times a week, but haven't seen any threads in regards to high idle. When I start my 2001 tundra v8 w/68k miles it idles around 2100rpm, which I assume is the "cold start". Once it warms up it idles at 1100rpm in park and 600-700rpm in drive. Is this normal?
The only problem the cold start has caused me so far is causing the truck to really take off, as I normally like to hop in and drive.

No this sounds just a bit to High for my liking.

Seems atypical to me too. Most tundra owners complain the idle is too low.
2100 at startup is really high. And a warm idle of 1100 is way high also. Check your TB, and the throttle linkage to make sure it's clean and not binding would be my first guess...

Ditto what the others said...1100 cold (briefly), dropping to ~5-600 when thoroughly warmed up.

Well I'll have to check mine, with 2785 miles I think the idle is high, the truck can run 20mph when cold, and I find it wants to lurch @ stop lights if I don't pay close attention... even when warm it seems to idle high............
about same here...1100 cold (briefly), dropping to ~5-600 when thoroughly warmed up.
After i cleaned my throttle body the rpms came up to around 800 when warmed up.
Your throttle control motor could be sticking:
1. REMOVE THROTTLE BODY COVER
2. INSPECT SYSTEM OPERATION
(a) Check that the throttle linkage moves smoothly.
(b) Inspect the throttle control motor for operating sound.
(1) Turn the ignition switch ON.
(2) When turning the accelerator pedal position sensor
lever, check the running sound of the motor. Also,
check that there is no friction sound.
If operation is not as specified, check the throttle control motor
(See step 3), wiring and ECM.
or
3. INSPECT THROTTLE CONTROL MOTOR
(a) Disconnect the throttle control motor connector.
(b) Using an ohmmeter, measure the motor resistance between
terminal 1 (M+) and 2 (M–).
Motor resistance: 0.3 – 100 W at 20°C (68°F)
If the resistance is not as specified, replace the throttle control
motor.
(c) Using an ohmmeter, measure the clutch resistance between
terminal 3 (CL–) and 4 (CL+).
Clutch resistance: 4.2 – 5.2 W at 20°C (68°F)
If the resistance is not as specified, replace the throttle control
motor.
(d) Reconnect the throttle control motor connector
Also make sure there is hot water running thru the 2 water by pass hoses that go to the throttle body. Make sure they are not plugged and the water is flowing.
