We study the device of the 1G-FE engine (part 1) - Toyota Altezza, 2.0 liter, 2003

Some time ago, there was such a problem: in the morning (the car is always in the garage, I don’t leave it on the street) at a temperature overboard of +10 and above, I start it up: it starts from half a turn, but it works at xx, then at 1500 rpm, then at 1000 rpm and then again at 1500 rpm and then it warms up and in the future there are no problems, errors, etc. It used to start and immediately at 1500 rpm and for warming up. The forum suggested washing the throttle body. I didn’t really want to climb in there and unscrew and remove something, so I decided to first throw off the terminal from the battery. It helped, but for one day - then the same thing started again. Today it was decided to still wash the throttle. To begin with, they sprayed, without removing the throttle, with a carburetor cleaning spray. Shit, of course there was a bunch (as I understand it, no one had done this before me). launched, everything seemed to be fine at first, they pulled the throttle, popped on the running car and away we go - the speed began to grow: 2000, 2500, etc. And what's the problem? Take off the throttle. They took it off, washed everything well with gasoline and also removed the idle speed regulator: the principle is the same as on the throttle valve, there is only a cylindrical valve. Well, in general, she hung in the open position. Raskodili, washed and her. Gathered everything to the heap. Well, God help me! Dryn and half a turn went and voila, the speed is normal and idle. Well, let's hope it stays that way! there is only a cylindrical valve. Well, in general, she hung in the open position. Raskodili, washed and her. Gathered everything to the heap. Well, God help me!
