can anyone help me?
idle, the engine runs very irregularly.
has been replaced replace the manifold and lamdasondes many of my doblo,
new spark plugs, ignition coils,
still there is nothing to find.
also by reading the Fiat dealership nothing.
suspected itself that there is contamination in the injectors ??
to consider themselves ????
is actually a fiat doblo malibu 2004 1.6-16V

Hi,
IF there are ZERO warning lights..:confused:
then I would suspect a poor electrical connection to a necessary component,
maybe injector, maybe coil pack.

are you 100% confident that there is no MECHANICAL problem,
low compression due to valve or cylinder wear. ;)

thanks for the reply,
I have no idea what it could be and IKM where to look,
when I turn it down quickly vanauit stationary road driving, but when he drives frequently than he drives super good !!! and I notice no difference,
I brake then back down to stagnant, he is again very bad,
pounding and stutters,
 
valve problem, from which valve???

on the highway, he drives very well and is also best sheet for a 1.6

I am now quite done with
my doblo 1.6 16v malibu will continue in 2004 but poorly run.
has replaced all very much and controlled.
replace manifold,
lambda probes
coils 4x
spark
Compression measured excellent
controlled injectors, excellent
throttle body control, excellent

continues as the engine warms up very badly run
when he drives he drives excellent !!

someone knows another tip

even the garage can not find anything and do not know

since you did a great job when you had a compression test, so I think it's nothing related to the engine, maybe the fuel pump is responsible for this I believe
 
yes

and Today I noticed that my accelerator pedal is not responding correctly
