Low RPM, high load is when the engine demands the best spark. More than likely you have a bad plug or plug wire causing this issue. You didn't say how many miles are on the car. It could also be due to a broken piston ring, but I wouldn't say that without knowing what kind of mileage was on the car.

misfires can come from faulty injectors, low fuel pressure in the manifold. timing , blocked exhaust. faulty o2 sensor, leaking inlet manifold gaskets, faulty valves (burnt) It is not always plugs and leads. Have a fault code reading done.

hav you check your plugs after it happens? a black plug will tell it has too much fuel, a wite plug no fuel at all, leads tours a faulty cold start injector, you can also try to keep it alive with carb or throtle cleaner if idles you not getting enougth fuel. keep in mind compresion test, and valve adjust, this engines require it has a regular service.

1998 boxter idle is perfect ,,missfire /backfire when rpm is incr


It might be injectors and/or fuel filter clogged.
Try to use injector cleaner (ask for recommended heavy duty in auto store) also I would check maf sensor.
Also misfiring/backfiring is a sigm of worn/damaged distributor cap/wiring
Please kindly let me know if this info was usefull/useless for you or you need more info
Good Luck
