Help with Contur 94 does not turn on

Hello friends I need your help I have a contur model 94 engine 2.o the problem is that it turns on but the revolutions go up and down and at the time of accelerating the engine is killed and a lot of gasoline is passed to the engine since there is a lot of black smoke

Hello everyone, Wichopit , I imagine that the model is a Ford Contour? Does the other have any fault witness (Check Engine) on when the engine works? Motor RPM oscillations are produced at idle or always? RPM oscillate from what range? Fundamentary a little info to help you among all. Greetings cordials.

Ok Fiat 147 If it is effectively a Ford Contur Model 94 Motor 2.0 The problem is that when I turn it on it is done until 1500 rpm for a few seconds but then the engine begins to tremble and the revolution He begins to fail as if he wanted to go out and start throwing black smoke the gasoline bijias and turns off if he has the witness on but I have no scanner for that model since it is Obdi and I only have the OBDII and thanks for your support

Hello everyone, Wichopit , my opinion is that it can be several things, if it is OBD 1 Ford Standard, the fault codes stored through a procedure can be extracted, in which in the obd1 clutch you make a bridge between 2 pins, with this the ECU Motor will give you the codes by flashes. You must count them, long flashes (tens) short units. Ex 2 Long flashes of check light and 4 shorts, mean code 24, then you go a table and identify the circuit failing, I don't know if I explain myself well ... With respect to the procedure it generally varies little in Ford Obd1, and there are many tutorials on the web to the respect (with photos included) of the bridge that must be made to the OBD connector so that the ECU enters the function of self -diagnosis and you of clues in the diagnosis. If you have problems tell us and if you have the codes better. As a recommendation, delete all the codes (disconnected battery) then turn on the engine and leave it work a few minutes, then do the OBD1 self -diagnosis (bridge) and let us know. This is so that if sensors or actuators disconnected, do not induse an error and thus have the real problem detected by the car computer identified when generating the fault code. Greetings to all.

Hi Wichoit, for the years that your car has, and these symptoms, I think that the caudalimetro can be measuring badly, because you say that it is to accelerate is when it begins to fail ... that is when "the air inlet" varies to the engine. It would be good to indicate at what time you turn on the brevering light, also if you can do it, the diagnosis, as Fiat147 says (what I do not are if OBD 1 is equal to Aldl eg Opel). I discard the problem of the gasoline regulator (I would not turn on witness), injectors (all wet spark plugs ...), but I do not discard a problem in the DIS or ignition coil, it has similar symptoms ... Resuming: Flow, or Dis. Greetings!!!
