There is a digital stepper motor installed in the idle air control valve and it is operated by the ecm after taking all the outputs from various sensors.
Check engine light error code 33. The idle air control valve circuit open or shorted to ground. There could be three possibilities which can trigger this code and the check engine light comes on.
1. Check the wiring harness for open circuit or short to ground. Check the idle speed control valve connector for looseness,corrosion of poor contacts. Jiggle the harness at various places to find any damaged wire.
2. Idle speed control valve defective. (replace. Merely replacing the electronic part of the valve can also solve the problem)
3. ECM defective. (replace)

Which is fuse for radio in 99 corolla ce
just look at your fues block with a flashlight and you will be able to see the blown fuse... look closely it might not be obvious at first. Another thing you can do is go to the store and purchase a fuse tester... a simple device that has a pair of pins (actually they usually have 2 pair, one for two different spacings) and an led... you put the pins against the fuse's exposed metal contacts on the flat back and if the fues is blown and the device is on, the led will light... you may have to buy a fuse kit to get the tester but they are well worth it, along with a fuse puller, if you are like me and have large fingers

My 1999 toyota corolla is consuming so much fuel.
first have the fault codes read
the consumption indicates flooding so it could be excessive fuel pressure, bad injectors , injector seals , blocked cat converter MAF/VAF sensor or heated oxygen sensor in the exhaust manifold
what the problem will be in the codes

Am driving a toyota corolla with a 4e engine type
Have a compression test done on your engine; my guess is low compression on those 2 cylinders. If that is the case, a rebuild of either the head or the whole engine is the solution.You might also check with your local Toyota dealer if there is an updated valve cover for that car; they had problems with the 3.0 V6 engines in that regards, not sure about the 4cylinder.

Leaking and burning engine oil. Black smoke coming from exhaust
There are only three places you can lose oil.
From the valve stems. This burns oil and it will be present in the exhaust. It is the least expensive to fix as only the cylinder head has to come off.
From the piston rings and especially the oil scraper ring, (two compression rings and one oil scraper ring). This requires engine removal, a rebore, new pistons and rings. This also causes oil to be burned in the combustion chamber.
Oil leaks from joints in the external seals to the engine, the sump for example. Also from the oil breather pipe. You can check this by sliding a piece of carboard after you park and check it before you drive next time. Any POOLS of oil signify a leak.
By you saying your oil is black, signifies oil is seeping into the combustion chamber and being partially scraped back.
Check the compression with a tester, and measure against what compression is supposed to be. You can Google this.
