Richjts - I think I am getting the exact same behaviour as you. At low revs in 2nd, when I demand some power (for example up a steep hill or pulling away after someone in front has just pulled off the road) the engine stutters, the warning light flashes up (demanding that I take the car to the dealer!) and then a few moments later the rev's pick up and the problem (and light) go away. The problem is always evident in the first minute after starting the engine.
I took the car to a specialist and at first we though it may be that the timing was slightly off, but that wasn't it. The mechanic thought it unlikely that the injectors or coil packs were the problem. He also told me that the error codes were something like "general misfire" at first on cylinders 1 & 3 but more recently on 1,3 & 4. So for this problem to be affecting various cylinders, I think it unlikely that it is the coil packs.
While the forum was down over the weekend I cam across another website which had some common engine failures and there was mention of a possible faulty fuel pump (Alfa Romeo Technical Help
) and this suggested testing the pressure:
* Switch ignition on and off every 10 seconds to check fuel pressure through 10 cycles.
* Replace the fuel pump if the pressure is not between 1.5 to 2 bars, making sure the reference arrows are correctly aligned.
I am thinking that perhaps at low revs there is less negative pressure "sucking" the fuel through the injectors since the positive pressure from the pump is "blowing" poorly. Then at higher revs the "sucking" action overcomes the low "blowing" pressure problem. I am assuming that the pump is electrical and so the engine revs should not affect its pressure.
I'm hoping that my local garage can check this for me quickly.
In the meantime I am going to try disconnecting the MAF to see if that makes a difference (but going by your feedback it sounds unlikely). I will also check the resistance of the coil packs. I have already used a bottle of injector cleaner and that made no difference so I am ignoring the possibility of an injector problem for now.
I'll keep you posted on what I discover.
