Another upset - Toyota Vista, 2.0L, 1989
I drove 400 km without problems and the hike began. Spontaneously (not always), but quite often there is a jamb with engine speed. When you press the gas pedal, the revolutions fall and the car stalls. In rare cases, they rise to 2000 and that's it, nothing else. You push on the gas harder, the speed drops sharply. Essesno all attempts to get under way lead to the fact that the engine stalls or "goes" km 3 per hour, twitching rhythmically. This mysterious behavior disappears as suddenly as it appears. I don't know where to dig :-(
changed filters for a long time? looks like a gasoline pump ... look at the candles, do not the explosive wires break through?
I will definitely wash under the hood, but it must be taken out of there first. I will do this because of the warmth, so that I can ride a bike to work. In the meantime, I'll go from simple - I will change the candles, the fuel filter))) and then we'll see
I had this when there were problems with the ignition coils ... you have a current distributor
it helped me, at least it seemed so))) in fact, there was a banal blockage of the power system directly in the fuel pump bracket. cleaned with wire, washed in kerosene, collected and drove)
How did you decide? Exactly the same problem was, it helped if the wiring was pulled)))
Lucky, I reconnected almost all the wiring with a similar problem, the old owner "tried"
