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
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!
