fiat sedici with misfiring

[saetta]

hi all, I have a problem with the car.

fiat sedici 31/12/2009 1586cc 88kw n engine m16a mount lpg system brc

the problem on this car and that after doing a bit of street lights the light engine is flashing and then fixed,and be fixed to three cylinders.
done a lot of work and tests in compression from cold to hot and in place,review head the petrol injectors and the gas injectors in place,the problem is always on the first cylinder P0301 checked the wiring, and to place in doubt or made to an external wiring, and is equal to,or tried to turn the injector spark plugs and the coils and disconnect the lpg system but it does the same,I did a test with a current clamp, and or saw that the commands,according to me there is an end that controls the injector that is interrupted by warm,what do you think? I'm attaching a print-out with the injector running of the second cylinder,and the one of the first that is not working.

[ugoboss]

you have not specified what type of injection mounts, but I think that is a problem of the ecu.

[saetta]

It is a bosch fuel injection , the impression that or is that the ecu turns off just the injector.

You said yourself, and a classic semiconductor.

Before replacing, do a test to be completely safe, hot-when you present the defect is a way to cool it if the open the better.....if you see that the injector starts replace ecu.

now I do not know the car in question, but here I have a bosch EDC 16 C8 147 with the same problem......cold perfect but as it warms it goes to 2.

The I want to try reading and writing the box in the bdm.

Instead or made the test reverse from cold and heated with a face, but saw that it had become very hot and I didn't trust to insist.

I suggested your test because it does not always work.

there are dederiminate conditions with which you experience the defect....for that you should wait to present the problem and then reffreddarla, better if you know the end of the injector indicted, and try to bring down temperature to the ecu.

now I don't want to get into too much detail, otherwise here who does not understand makes fun of me because it does not know of what I speak, but sometimes you have a single chip power management of the injectors which, in turn, have within them the end that manage it are usually the mosfet.

there is also the possibility that instead of wanting to the power of the signal pmw and off the injector, the reasons are even more profound....but always the ecu at the 90% defective you speak.

I advise you to wait for the defect and try to cool down,all this with the engine running.

do not use spray chilling, the temperature drop is too sudden it could create additional failures, to do this you should know the thermal characteristics.

[saetta]

Ok thanks for the tip, today, or sort the ecu we'll see what happens.

[MustangGT]

let us know, and always interesting

[saetta]

Yesterday, the ecu, the assembled and coded the keys,the seal in the bike quite a bit and it seems that it does not do so,on Monday I do another test .then I'll have to refit everything you removed.

[MustangGT]

it could not be more....*****and I have the herringbone on the reverse test often does not work....you have to see it hot-in which the condition occurs, the defect and then cool it.


in fact, the controls that you have made there are before blaming the ecu
