Afternoon all,

Travelling home from work yesterday, my fuel injection light flicked on for a couple of seconds an went out. At the same time I notice a slight loss in power. I continued to travel on and didn't noticed any loss of power since but the light did flick on and of again momentarily. My questions is, is this the start of a malfunctioning fuel injector or is it simply a blockage of some sort. Should I have this checked out at an Alfa Service center immediately?

Any comments would greatly welcomed.

Cheers

Mine (2.0 16V P reg) does exactly the same thing. It does say somewhere in the owners manual that it will happen from time to time and not to worry about it.

Thanks lads, my arse was really going for a minute. The cars due for it's 48K service soon so they might pick something up then.

Thanks anyway.

The light usually indicates that there is some sort of malfunction or a reading from a sensor that is not plausible (e.g. air temperature higher than 70° C).
In a lot of cases its a worn Oxy sensor, there is an inner adjuster that is just able to work within a specifc range, if that range is exceeded, the ECU will store an error code and that light will come alive. During the malfunction, the EC will use a "limp home mode", that means it uses a standard mapping in order not to ruin the engine - that's your loss of power.
On my 33 P4 and on my 75 TS I am able to read out the error codes myself, but don't ask me how it works on a 155.
Maybe your dealer is so kind to read out the error codes of your car without ruining your financial perspective - its a real fast and easy job.
