Hi,
my Punto Mk2 ( 16v ) shows an annoying behavior. While idling the engine has random and frequent cutouts, i.e. a cylinder isn't fired. This leads to a mildly shaking car and a not very healthy sounding engine, especially when the engine is warmed up. While driving I don't notice any cutouts.
My authorized garage wasn't very helpful. They said that the computer diagnostics doesn't show any problems and they have to replace some expensive parts trial and error to locate the problem ( throttle valve or electronic control unit ). It's obvious why I'm not very happy paying around EUR 500.- for such a proceeding.
Are there any known issues with this engine that could cause the problem? At least it should be clear if the problem is connected to the fuel injection or the ignition. I suppose that not fired petrol could cause some damage to the catalytic converter. But the exhaust emissions doesn't smell of patrol ...
I plan to switch to an independant garage which may has some more motivation to locate the real error, not just exchanging whole units. What should they check? Any hints?
Thanks in advance!
Bye, Jan
