I've a '97 Fiat Punto 55sx. It was last serviced last week...
The problem I have is that starting the car up is fine, the choke kicks in and no problem. Then when the engine is off cold, but not yet warmed up, say after a mile or two, there is this high pitched "squeal" which jumps in at around 2,000 rpm, and goes up in pitch as the engine increase rpm. When the engines at 2,500 rpm, the noise stops. Then, say changing from 3rd upto 4th, when the rev counter drops into that range again, the noise starts up again.
When the engines warmed up, (say driving at constant speed for 3 or so miles), the noise fades off an stops altogether in town driving.
I asked the mechanic where my car was serviced and he said that the Fiat probably came with a valved choke system, and that may be the problem, adding that I shouldn't worry too much about it. Had it serviced at the beginning of March too and only told that mechanic about it afterwards, it had been happening for a week or so then, and he thought maybe the alternator was dropping correctly? (I know nothing about the mechanics of a car by the way!)
Anyway, the last week it's gotten worse and will come in again after 3,000 rpm and cut out again at 3,750 (or so) rpm. It also lasts a lot longer and have noticed that it's still been there after even 8 miles of driving on a motor way.
Any ideas?
Is it something serious?
Costly?
Thanks for your feedback, in anticipation.
