[Vwdiesel] Re: New problem high idle

[Chelly Bennett]

Are you using a fuel treatment?  The first 1.5 in my 79 rabbit would do this if I
was using power service fuel additive.  Howes, dextron atf, or straight fuel
didn't cause this problem.  Even mixing in a little jet a wasn't a problem.
Seemed with power service additive that about 1/2 way thru a quart bottle it would
start hanging up at high idle and then slowly return to low idle.  Stopped using
it and the problem would go away.  Tried it a couple of different times, same
results.Justin
