My Honda Civic Lx ('98, 115k) makes a sport car like noise
(Papapapa...) when I step on the gas, for about a year now.
It makes noise ONLY when the car is moving, if I step on the gas, and when the engine is relatively cold (less than 10 minutes after the ignition).
Do you have any clue?
Many thxs to J & RB for your quick answers
Is this something for diy or should I ask
help from a mechanics?
