Opel Vectra 1993 problems

I have an Opel Vectra Year 1993 Monopunto, the problem started when the light of Chech Engine Plpaadeo, Sensor was changed such as IAC valve, TPS, Lambda probe, temperature sensor and the prromblem still continues. When the engine is hot, the prromblema is resolved but when the vehicle appears, the start is dicularous, before when the engine turned off it turned it without stepping on the accelerator but now I have to step on the accelerator thorough

The first thing you should do is scan the engine, then change the pieces indicated by the fault code. Because you write a problem of excess fuel.

I agree with MZ1771, the first thing is check, but being an Opel Vectra and for the symptom that you describe the most likely you have problems with the temperature sensor is not a face face and it is easy to change, check and let us know.

You have seen the sensor that goes from the lid of Valancines to the motor block under the exhaust connectors, it is the oil sensor, and you advise you that you do not change the density of the oil, you can volber crazy to find the fault and then you have the surprise that is of the oil ...

Hello, you have to start by discarding possible shorts or wiring break before changing pieces, I suggest that you delete the codes and start the system you have a handling test and rescue the stored codes, and as the faults appear as you start the corresponding revisions.
I hope to help.
