VOLVO C70 BATTERY DIED REPLACED NEW BATTERY NOW MISFIRING AND ROUGH IDLING
Hi recently my battery died, so i went and got a new one gave the company my reg and they supplied me with a new battery. As soon as id fitted it my car was misfiring and rough idling, ive noticed on my old battery reads 70hp on the sticker but the new one reads 72hp, i phoned them up and they told me that the battery would have nothing to do with the problems that have occured, but the car was running fine until i fitted the new battery. please help.? i just dont know what to do :(
