VOLKSWAGUEN 1.6 2004 INJECTION MARELLI

Sorry, I was happening to me if it can't be the MAF sensor, air flow, but I don't know where it is in this car, and I don't want them to get me more money ..., if anyone knows please locate me !!

Your car does not wear air flow sensor wears MAP admission multiple pressure sensor, and is a black square with two screws and a connector that is in the admission manifold. You have to check your Lambda probe or oxygen sensor and also the minimum gear valve, with the scanner you have to check the reading of the computer voltage since there is a relay that supplies this voltage and suddenly fault and produces minimal variations, another sensor that makes them fail a lot is also the water temperature, but to check them you have to check them.

Knights, I tell you, the problem was in the butterfly body sensor, which handles on the computer the opening or closure for the relash, this has no repair and change, end of the problem, in terms of the counter -explosions the distributor was run, it has a larger window than the other 3 and marks the cylinder nº1 this makes the motorcycle put to the motorcycle by the computer, it was arranged.
These cars with multipunto injection are one why, better carburetor and combination electronic distribution.
Thank you all for the interest and for trying to give myself a hand, I sell it and I buy a Chevy Flower 1978 SS 250! Hahahahaha
