croma 1.9 150 bhp vibration and engine block

[michele30]

today I ? arrived in off. a customer with this problem:

the ? happened several times that while it speeds to change gears ( machine already in motion ) just above 2000 rpm, the machine stops and goes in vibration throughout the engine.. but if you accelerate it takes not even gas , and the engine vibrates at all.

approaching a moment, always with the engine running and after a minute ready to leave and the car ? ok.

the lights all turned off.

machine with 90000 km

egr and dpf off, done already, but I said that this was also happened a few times before delete the dpf.

I ? a successful cao similar on a 147 that when he was about to die because of the effort, not just pigiavi the clutch to avoid turning it off and began to do so, vibrated very strong. Was the flywheel (dual mass)

[giuseppe1374]

get him a diagnosis,it could also be an injector

[alfajtd]

I suppose well I'm the fly half broke...

[explode82]

I don't think I own both the flywheel and since when is this defect does not accelerate even check the injectors and the pressure of the rail when doing this defect

[demolitionMan]

The exclude a priori! if the machine goes 3 vibrates a little! and then accelerates anyway.

even in the case that I could not accelerate,but you had to turn off the car. for? the defect in this case is manifested in different conditions

[giuseppe1374]

ragionandoci well the injector does not ? but not why? as you say, the machine goes to 3, and vibrates a little why? if it goes to three enters in protection and should turn on the light engine at least when ? was defappata have been removed from the-bit dct and does not mark anything on the dashboard. however, with a diagnosis we might know more?

hello the problem may be the group butterfly that closes plugging the air passage.. me ? happened.. on pi? engines (1.9 and 2.4 mjet.. in practice oxidize the wires that go on the throttle unit and are in contact with each other or to ground.. or the wires of the temperature sensor coolant which is not far away.. on the threads of the air mass meter that sfregavano with a metal part.. cmq made various checks hello..

[giuseppe1374]

if ? the group farfarlla should not turn on the light engine? or ? as I say in the luca stanca have been removed in the dct.

[explode82]

put it gold and make two tests at this point ? the only solution to understand something

you say that it vibrates a little why? I have done tests on the same engine! and it gives you the dtc if you disconnect physically the plug of the injector! but if he has a physical problem , difficult throws you out of the dtc! if ? been used ecusafe ? likely that you have disabled the dtc!

[giuseppe1374]

yes I am agree with you but the thing ? what I don't understand ? that the car will not accelerate and it vibrates, apart from the fact that with a problem like this the way failure should turn on, the vibration should be a sign that the motor should not be equal, at least that are more? problems, the only ? make a diagnosis certainly avr? stored the error.

We look forward to the diagnosis ! we need to get it!

there are notiv

Hello everyone!!!!
Joseph, I've a little time f? the same problem at the same machine..
the car is totally original with 60-70milaKm..
the beautiful the defect to me and happened to you personally after having made a forced regeneration!..
and in diag. no error!, in the parameters everything is perfectly in normality?..
then never again? resubmitted..
I think it is always in the de-fap the problem..

[paolo159]

verification of the correction of the injection cylinders with the diagnosis, ? very likely that there is an injector perfectly calibrated, or that goes in the block....if the correction goes above 3 mm^3, the motor begins to vibrate..

The mimimo ? regular?

[explode82]

sometimes can? also be the regulator of the rail on the flute,me ? already happened

[andrea58599]

Hello all, me ? the same thing happened, the engine that vibrates and strattona, no is on and no error in diagnosis, in the end, I found the intercooler cut at various points, replaced the piece on the machine work again-well, obviously before the replacement smoked black.

[dariuccio]

I think, too, to a power supply problem, even why? the flywheel and most of us is in the early stages of departure.
I think I, too, injectors, or the control valve pressure.
in addition, if the injector is electrically operates and locks only the mechanical part and go quiet that diagnosis does not
see nothing

hello,I have happened to 2,if the engine vibrates a lot and is certainly the volano.la before it was only in the starting times, and immediately I thought I had solved it by changing the battery because it was a bit down' and the mot start filming plan,but after a couple of days and it came back with the same problem .the other, instead, it made him even if you fermavi to a stop sign, or if the gear shift to the left down turns it on purpose,it seemed that drop below the threshold of the minimum,changed the flywheel all posto.a oh, I forgot, made a lot of noise but when it was on the defect...

[rosspigna]

Hi.
I suggest you to upload the original map and make a test control units for read errors, as the problem should turn on the malfunction indicator light.
