Will cut to the chase. I just got this car from my mother. She had alot of work done to it before bringing it to me. On of the things I guess the mechanic missed was that there was a CEL for a misfire on cylinder 3. I figured I would replace the spark plugs and see if that would help. It turns out they had been replaced before but evidently the previous person had as hard a time as me finding the 3rd and 4th plug. I hadn’t ever seen them were they hide them under the coil packs. Anyways that didn’t fix the issue. I know from the mechanic that it is getting proper fuel pressure. I guess my questions are as follows. How can I figure out which one cylinder 3 is? And what is left to change? Just the coil packs I think but wanted to make sure I wasn’t missing anything?  
  
  
  
 Thanks All.
