Paul,
Steve is gonna go nuts looking for his brake booster and/or the vacuum line
cause his TR4 doesn't have one.
But on a 250 or a 6 a leak in one or the other would be a possible cause of
his idle drop. He'd also hear a sucking sound under his dash if it were the
booster/servo....know it all too well...two boosters in the last year.
Which reminds me does the list know anyone that repairs brake boosters? I
thought I remembered talk about one in San Antonio and maybe one in Ft.
Lauderdale but of course I can't find the info.
Thanks
Bud
