Issuzu Rodeo 95 Ralenti problems

Hi, Isai182 The other thing that would help enough is to check the engine spark plugs one, paying attention to their color, accumulation of waste, etc (dynamic imbalance) of the engine. Ex: If you disconnect the number 1 injutor and the RPM fall, it means that the combustion in that cylinder is acceptable, if you disconnect the 2 and there is no change of rpm and softness of operation, it means that combustion in that cylinder is bad or non -existent .... Finally, nothing of the engine compression ... would be ideal Admission under different conditions (vacuometro). So patience and more patience, it is the only way to detect rare failures in a system of modern electronic injection ... I already hope to wait for comments. Greetings to all.

The broken diaphragm of the EGR can be making a false admission air take after the MAF, try to plug the empty tube and leave the EGR closed to see what happens. Greetings to all and especially "Fiat 147" !! (Time you didn't write)
