Re: backfiring

Nina:

Does your car have an air pump?  If so, frequent backfiring when changing
gears is often a sign of an air pump going/gone bad, particularly if the
backfires are through the exhaust rather than the carb.

Try removing the pump (temporarily, if you like) and blocking off the air
rail (ditto) to see if this solves the problem. If so, then you'll have to
look to either have yours rebuilt or re-do the engine without the emissions
equipment.
