zx volcan problems
hi, I have zx volcan 1.9i 92´, I have two minor but annoying problems : 1. at 2k rpm and at 3k rmp, in any gear, with little pressure on the gas pedal the engine has vibrations - like in old cars after cold start ("gihukim" in hebrew...). the car is prefectly maintained. 2. when going in down-hills and the engine is braking the car (any gear), there are small back-fire sounds from the exhust, plugs were changed 8k km ago. my mechanic recommended to change fuel from 96 to 98-99 (which is unleaded but still higher octan). it didn´t help. any idea ?
