Ferrari Mailing List: Re: Bosch K Jetronic Ignition

[Dave Handa (dave]

As Jeff said, the fuel injectors can and do often leak.  If the car still
has the original Bosch steel ones, then by all means replace them with the
newer brass ones from Bosch.

I think this was previously mentioned, but there are three typical
components that most often contribute to hot start problems when they fail
or leak.  Fuel injectors (including the cold start valve, which is just
another fuel injector on the intake manifold), check valve, and accumulator.
They are other things too, but those are the first to check.

Dave

Clyde - 

With all do respect, CIS injectors are notorious for causing problems.
Whether or not they 'actually fail' is debatable, but I have never seen
anything other than a new CIS injector have a proper spray pattern.

I've been working on cars professionally for more than 20 years, and have
seen more than my fair share of CIS cars over the years. More so in the past
when CIS was common on MB, Porsche, VW, Audi, etc.

Modern pulsed (ie electronically controlled) injectors, are another story.
They seldom fail, clog, or cause problems of any sort.

Most likely the fuel accumulator is going south.
Check that 
I have never had an injector go bad.

Hi all,

would anyone on the list have digitized information about the K Jetronic
ignition found on the 328 ?

I'm specifically looking for tuning and troubleshooting and someone
mentioned that there is such a manual from Ferrari itself.

Thanks !
