I own a '99(V) facelift model 145 cloverleaf. The car always starts OK, but after a minute or two it starts to run erratically, i.e. it judders if I'm driving along at 30mph or if I'm sat at traffic lights the revs will rise and fall wildly until it (sometimes) stalls. Putting my foot on the accelerator also seems to flood it.

Once the car has warmed up to full running temperature it's absolutely fine.

Does anyone know what might be causing this?

Cheers,

I've ordered a new water temp sensor as it's only £15, so I'll try that first.

Can you remember how much a new lambda probe is (a lot more than £15 I'll wager)?

Should an Alfa dealer be able to diagnose the problem by 'plugging it in'? I did ask about the problem at the last service I had at an independant specialist, but they said that the ecu wasn't showing any faults and that problems like this can be difficult to diagnose.

Mine was diagnosed by an independent auto electrician; I can't remember whether it showed as an ECU fault code, or if it just showed as an out-of-spec value on the diagnostics. As for the cost, I don't know as it was done under warranty. It's always best in these circumstances to pay a few quid & have a diagnostic check done rather than just go ahead indiscriminately changing components in the hope that you hit on the right one - in many cases, when you fit the new part the system has to be recalibrated, so you'll need the diagnostic equipment for that.

Four days after buying my 146 Ti (13/11/04) it would start but cut out as soon as I took my foot off the gas. On the move it would cut out as I slowed for junctions. I took it to the guy that had serviced my previous car, who admitted he was unfamiliar with Alfas, but would take a look. By chance a mobile auto electrician was on hand and was given a free reign. I collected the car after paying £30, the engine sings the sweetest song, but I don't know what the fault was, only that it is no more!

when ever mine starts tickin over wrong, twice since i've had it its been the steeper motor stickin which is freed by takin it off and squirting some oil inside and workin the flap! I have had the lamda sensor replaced for its mot cos the readings were sky high but this didnt cause the car to run as you've discribed. :confused:

Hi All,

An update to my original post - I did what Dave Brand suggested in his post and took it to my (not particularly local) Alfa specialist, Red Motori. They plugged it in and diagnosed a problem with the Lambda sensor, so I had it changed and now it runs like a dream ( :D )!
Cheers,
Chris.
