RE: [alfa] Re: Milano Cold Start Injector Problems continued

["Jeff Greenfield" <alfaguy@xxxxxxxxxxxx>]

Two thoughts ...

1) have you checked the thermo-time switch which turns the cold start
injector on? If this is bad, shorted, etc, the injector could be firing all
the time. If there is no change with the wire to the cold start injector
disconnected AND the cold start injector is not leaking, then this is not
the problem. (or at least not all of it)

2) how about the coolant temperature switch? If this is bad, the car will
start up more or less ok when cold, run ok for a few minutes and then run
very poorly if at all.

In either case, I doubt it is a problem with the crankcase vent system, I
suspect by removing the oil cap, you are creating a vacuum leak which is
masking the problem by simply allowing extra air into the system ...

HTH,

Jeff

 I have changed the cold start valve and injectors with ones that was known
to be good. I still was having some trouble. Upon checking the oil, it was
found that about an extra quart of gasoline was in the oil. (not good). I
changed the oil twice and the car would run fine until it sat overnite. The
next day it would not start and the plugs were fouled with gas. I sssumed
that there was more fuel in the oil and was evaporating up into the intake.
So, changed the oil again. I started the car and idle was fine for about 5
minutes, then would start running rich even if the cold start valve was
removed from the intake. BUT, I removed the oil cap and the idle would
smooth out. Also, after driving the car, I can remove the oil cap and the
car will start the next day. I now think that the crankcase ventilation is
somehow clogged. Will be checking that out today. Any other suggestion will
be appreciated. This has been a head scratcher for sure.
