Think of it as you would taking a car to the shop for repairs. Unless you're an experienced mechanic yourself it's better to say "When I try to accelerate after a full stop, the engine hesitates for a second or two, then I get normal power. Occasionally the engine stalls and I have to restart it. Once I'm up to speed everything seems normal" than "I figure a boojum got into the framistan glamis, the grankwell's trunnion has gone skewgee, and that defrobbed the bilge patinator. Oh, and take a look at the henway while you're under the hood."
If you really are an experienced mechanic, go ahead and deskew the trunnion yourself — assuming you've got a full set of widget glampers and a suitably pligged momplitude adulator, of course.
