Issuzu Rodeo 95 Ralenti problems

Thank you for being interested, the truth is that the cold car starts well or accelerated and normal the problem is that when the revolutions when heating down it is where the problem begins, it has very good power and something that I forget to tell is that I put the lighting of the alrevez coils and matches enough that towards a small explosion then I returned to the original ignition and notic manually improves only a moment and when closing it fails even more

Hello everyone, Isai182. If the engine starts in cold, accelerated slightly and then when the RPM falls gradually, a priori the idle control system should be OK. If then when the problems begin, you should check air inputs by admission, if this you should also notice that the engine suffers a slow return to the idle ... that is, ascending it abruptly takes more than normal to return to its minimum march state ... I do not know if you understand me ... also check air inlets between the filter and the flow or maf. Also an oxygen sensor or Lamda probe with slow response can ocation in rare cases the symptoms that describe, disconnect them and try (eye that can turn on check), if this happens last disconnect the battery for a few minutes and ok. I do not understand well as far as the ignition is referred to ... greetings to all.

It is a very rare case I am like the 3rd or 4th person who sees it and nothing, all the admission packaging has been changed. When do you say that the disconnect also would have to improve or get worse?

Hello with the engine at operating temperature, you disconnect the lamda sensors before the catalyst and the engine is normalized can be a slow response sensor, if it behaves the same is something else. The other imagined that the spark plug cables reviewed or changed, which for the year of the V6 Isuzu should have an ignition without a distributor with 3 double coils, is the ignition system so? Depending on the country and emission standards there are small changes in the emission control of these engines (double lamp sensors, one for each cylinder or simple bench, etc. Greetings.

You are right with the coils and cables, spark plugs and even the coils have already been changed and the EGR has been changed and the gasoline pump was changed to it, the time strip was rectified and I will not improve now I will try what you have recommended and tell you later I thank you very much
