Help Please - No power
Yet another problem with my 147. Over the past few weeks I felt power has been a little down, getting gradually worse, and this week, Its definately gone. On way to work the other day, going up a slight gradient with foot flat to floor the car actually slowed down all the way to 60mph!! It has a reluctance to rev above 5k and will also try to stall if you put your foot flat to the floor with the revs too low. Lightening your touch on the throttle stops the stall. The MAF I changed not long ago, so dont think its that. Ive tried unplugging it anyway, and no change. The plugs were changed last week, and when I changed them I snapped a coil pack, so bought a second set from a breaker and changed all those too, and it was loosing power before then anyway. I have run a tank of injector cleaner, and also suspected a collapsed cat, but it passed an emissions test yesterday. Does this definately mean the cat is OK?
I purchased AlfaDiag yesterday, and it is showing no fault codes at all. Im not that familiar with AlfaDiag though, so is there anything I should use it to check for?
Can anyone give me any pointers at all?
Any help very much appreciated!
