need help....car backfiring
car backfires when left in gear during deceleration. Popping ceases when clutch is depressed. Any diagnosis? I heard it could possibly be an exhaust leak.

Engine braking is slwoing down combustion faster than fuel is burning quickly. Every RX-7 I know of does this whenever you engine brake from high rpm. Basically the stock rich fuel map and oil injection leave too much in the chambers for clean burning.
Especially when a nice big fireball pops out!
