Hi folks,

I'm from germany and are owning a restored CRX 1st generation, ZC engine @125HP.
The problem is that the engine is sometimes bucking during acceleration, not depending on the rpm or gear which is used. Additionally, the rev meter is bouncing up and down.

Is this a known problem and can anybody tell what could be the problem? mileage is 130.000km and I assume it's still the first distributor. But distributor cap & contact are already replaced from previous owner. A new gas filter has also been installed.
