I got a 91 civic with a Zc DOHC motor. It out of blue started backfiring and loss of power. i dont know much about cars so im not sure how to figure it out. Since its a ZC motor im not even sure what book to buy to check to see what the timing is supposed to be. I recently (6 months ago) changed the distr. And had no problems since. PLease help.
