1984 1.9L WBX auto trans on shakedown cruise before taking Mrs Squirrel
out camping.

This surging began two days ago while climbing up a 7% grade and after I
passed the 4,000 ft marker.

Engine would run fine for about 60 seconds, then lost power, as if I had
taken my foot off the gas. After about 3 to 5 seconds, it would pick
right back up again. Wash, rinse, repeat.

Engine was warm: temp gauge needle one needle's width to the right of
the coolant level lamp.

Once I got to the top, flattish driving, no problem. Downhill, no
problem; flat terrain near sea level, 60mph, no problem.

I'll be taking Mellow Yellow into the shop -- what should I tell them to
look for?
