2007 Toyota Avensis MK2 1.8 VVTI Petrol T25 revving

[Johnnyg7uk]

Hi Folks. I have a 2007 Toyota Avensis t25, MK2, 1.8 vvti, petrol, manual, saloon vehicle.  

When the vehicle first starts up the engine seems to rev up high, sometimes up to 1800 revs. 

If I've been driving around in the vehicle so that it is warmed up and then leave it and return to the vehicle a short while later, when I start up the vehicle again it revs high again. 

Can anyone tell me if this is normal for Avensises or if it is a common problem with them?

Many thanks, John.

Hi, i would open the hood, take out the air filter sensor, clean it, put it back.

take off the big pipe that go into the engine, take carborator spray and clean the throttle inside and outside with clean soft papers or so, inside use your hand fingers to open it and clean the back of it also, take all the black dirt off of it, put everything back, turn it on with leg on the gas, after 2 days the computer will learn the new values and it fixed.

good luck.

Elevated RPMs are normal during the warm up phase, but 1800 rpm sounds excessive.

The 1ZZ-FE is known for fouling idle control valves. I would take the valve out, clean it, lubricate with silicone spray and reassemble. Second task would be to look for vacuum leaks in the intake tract.
