This evening (yes - Christmas eve) my daughter's '93 Accord LX (225K miles)
suffered a short bout of engine failure. She described it as surging a
couple times when she tried to accelerate, then the engine died when she
braked. I quizzed her about the tach and she was clear it was jumping rather
than swinging with the engine. It didn't start right away, but would sputter
occasionally and eventually lit off as though flooded (which it probably was
by then).

The Main Relay and ignitor are each about a year old (but both are NAPA
aftermarket, since the car insists on breaking down on Sundays and
holidays). The timing belt is 4 years, 60K miles old. My son and I replaced
the radiator about 2 weeks ago, so I am wondering if we stirred up evil
spirits in the process of that. He bled the system carefully, but a leak in
the lower radiator hose attachment may have let air in. I haven't done a
visual inspection yet, but will in the morning.

What comes to mind? Ignition switch? Some particular underhood wiring?
Distributor? Something I'm forgetting? She is committed to driving to San
Diego in a week or so and I'd sure like to sort this out by then.

TIA

Mike
