____________________ ORIGINAL MESSAGE: _____________________

this vanogon started doing this wierd thing. every morning
when you first start it up and drive off in the first two
minutes of operation it starts bogging down flip it into
neutral at floor the gas pedal it won't rev up it just
idles. its like it loss its advance for the igntion if you
turn the key off and restart it everthing just fine it only
does it one time from cold to warm runs great the rest of
the time.its a digifant system . these have alot of
promblems with the control unit i've put alot of control
units in these before but this one is crazy?
