Toyota celica vvti, year2000, 144.000kms
mine has a problem now, when I turn it on it doesn't go beyond 1000rpm, and when it heats up, it goes to 1500rpm, and sometimes it goes up and down from 1000 to 1500rpm.
Normally, before that, when is ok, it started at 2000rpm, and when it warmed up, it stays in 900 rpm. what could it be?

but having lost what in old cars was called a shock (cold start), where the rotation jumped to 2000rpm («/-), is this a symptom of the need to clean the idle valve?
Sorry it was what caught my attention the most, and I know this is regulated by the ECU, commanded by......Idle valve?

Thank you very much for the clarifications, they are very useful and of excellent technical knowledge. I just asked you the following. Can you send me a photo of the location on the Idle Air Control Valve car (IACV), and some tips on how to maintain it? if it doesn't bother you, and if it doesn't give you too much trouble, of course.
Best regards
ER

Ok, thanks for the precious tips
I forgot to say something that might add more for me.
I have the toyota celica stopped, I go for a drive on Sunday morning, for about 10 km. Is this what leads to these problems, I have two more cars, a toyota 2.0D 1998, 2C-E engine, for the day to day day and a lexus IS 220d for Sunday, the Celica is a collector's car, so it's parked

Yes my engine is the 1ZZ-FE, vvti, without the lift l. to date, no engine light has ever appeared, but the idea is that there are some rubber gaskets in the intake manifold, which wear out and need to be replaced (may not be my case, because the celica has 144.00km and I I ride it as an adult, 1500 to 2500 rpm, a maximum of 3500 to 4000 rpm on the highway). But there is one more knowledge of a maintenance point to take into account. Thanks

costs must always be in mind, without sacrificing quality (between us, without making a fuss, as it is not adequate). I recently changed the Oil Pump to my Corolla 2.0D (367,000km), the oil pump on Toyota Portugal, it cost 300€, I got an AISIN...., for 60€, online. We have to search and explore, the oil pump is original, Aisin.
