Hey all,
I am still having problems of a rich running condition on my digifant
fuel injection.
These are the things i have tried.... and checked..
1. Replaced temp sensor number two.
2. checked afm per bentley test... checked out ok.
3. Cleaned up ground for hall sender.
4. Checked the timing and adjusted idle.

I am now convinced that the van is running rich when cold...but also
when warm. Although the rich running condition seems worse when cold
than hot. But it i am still seeing a bit of black smoke when it's
warmed up when in neutral and i rev the engine. Again...this is not oil
smoke....but smoke from to much fuel. I can smell it.
I am sure that my hard starting of the van if it stalls before warmed
up is related to a rich running condition. Starting while the engine is
warm is also not the best...but it does start with a few cranks and a
little throttle.

So my questions are this...
1. What other grounds should i check and where are they located? I am
working outside in the cold...so the quicker i can find them... clean
them and put them back together the better.
2. I cannot hear my idle valve operating... but if i unplug it... there
is a change in the idle. The idle valve checks out per Bentley for
continuity and voltage reaching it... so i know that is ok. Has anyone
had a bad valve even though it checks out per the Bentley? On my old
Golf...i could really hear my idle valve hum...but on the van...not
so...

Any help would be great...
Otherwise i may have to suck it up and take it to the local VW shop....
IF there is anyone on the list that lives close to YORK,PA that has a
garage that i could use for a day to do the ground trouble shooting so
i don't have to freeze while trying... that would be wonderful. My wife
will make you yummy homemade cookies!!!
thanks,
jesse
