fiat bravo 1.6 120 hp faux recovery..

[michele30]

I have a bravo that ? come to me in the workshop after the other for a strange defect, is a defect in strange and sporadic, that is, the lady that help the happened more than once that went in ( recovery) on the highway look at the case when it was overtaking.
In the diagnosis from the air flow meter , they have already replaced both the air mass that the sensor on the manifold, I, instead, this Friday I replaced l solenoid valve that controls the turbo why?!? the fault we did it only once and when it was a plan, but ? so strange.. e.g. I did coming out of a step then the first and second then giving it the gas does not have the tablet, but gradual, the machine is not walked, sluggish sluggish as when ? in recovery, giving it all the gas ? changed nothing, then lightened the accelerator and the car ? back ok without any more to do with the defect , at least for those miles that I did.
I don't know if I did not understand in the explanation, is there ? never seen anything like that?
Proven with a diagnosis attached has not made a fold.
What I don't understand ? why? deverilevare this defect, I think as you close the butterfly valve and then suddenly it re-opens.
What do you say?

[marcogti]

The machine ? the original, or has had mdoifcihe type egr, fap, or other ? sempba almost a recovery for an overboost too high that could be related to a problem with the variable geometry of the trubina.

[michele30]

To be honest, the car I do not know if ? mapped , I have not read the flash.
for? why? then comes out a defect on the flow meter ? And why? does not stay on the rec?very, according to you?

[legendaryslave]

the exit of the defect because it pulls less air than you expect-now it's up to you to find the why

[giuseppeturbo]

how many chilomerti has the machine? test to see if the axis of the turbine has the game ,both axial shoulder ,if the turbine is not pushing, not sucking in air , see if the egr is not stuck, and then I can't remember if that machine has the butterflies, check out the butterflies on the collectors

[SandroMarciano]

this motor is provided with the swirl, I still would check the variable geometry, me ? the same happened on a mazda 3 1.6 hdi for? reported low pressure manifolds, but the problem (as it was) was identical to yours!

[ugoboss]

in the meantime, what do all the tests recommended, chiudigli also the egr with a blade.

Thank you for the info , however the machine ? new you can say only 80000 km .
The bad and the ugly ? that this defect does when she wants to, doesn't it ? you can carry it in certain conditions to make them do so, why? the breast with the computer in the car, see what happens in that moment.
I said to the butterfly valve, the one at the entrance of the manifold, why? I ? happened on a insigna that worked well from the active diagnosis, and then when you were starting was always closed and he didn't, of course ? a different thing, however, by following what it says on the defect leads me has to think so.
Then give an eye to the geometry, if you see anything.

I had success with a similar problem on a volvo xc90 after about 200 miles of highway had lost the power, the client noticed only when he was overtaking. Crashed the variable geometry in this case

[beppe.c]

that cod gives you a error?error-meter value is too high I low?
I purirei or disattiverei the egr valve I think it is them with the problem.
