Problems with overflow part 3 — logbook Toyota Corona 1990

Thank you very much teammate Sobaka_63 that advised diagnostics. Today he had, checked everything on the electrics, a completely different level in comparison where I was before. In general, from the beginning I determined that the pressure in the nozzle is large, it pours for the whole hu% nu. I began to look at each sensor and check the voltage at each. In general, I found that there is too much voltage on the vacuum sensor (I don’t know what it is called correctly). This sensor monitors that if there is no vacuum in the injection system, then the damper is open and gives a signal to the brain to pour benz as it should. He began to check the hoses suitable for him and found a hole in one, frayed over time. That was the whole reason. I replaced it and the revs straightened out.

Then I began to look, checked the oxygen sensor, it does not really send signals to the computer at all. It is also under replacement, one of these days I will drive up, change from dozens, since dozens have a four-pin (and the original is 2-pin) and connecting it in a special way, it will send a faster signal to the computer. Found early ignition yet. The distributor will need to be tightened.
He also advised me to change the candles, but I ordered them already.
That's all the problems.
Because of the hole in the hose such a hemorrhagic.

One of these days, this issue will probably be closed to the end, with the replacement of candles, a sensor and ignition settings :)
