Service Engine Soon Light: P303 and P316 codes given
2002 SCrew 5.4 V8 - 100,025 miles.
Last week my Service Engine Soon light turned on. I had a friend pull the codes with his reader and I had a P303 and P316. Doing my research I saw that they were the misfire detected codes for cylinder #3.
Search this board and on the internet I found that possible fixes to this problem is to change plugs and the COP which I did (replaced all plugs and the COP for #3).
Still have the service light on when I started it back up after I was done. Will have my friend check the codes again tomorrow (Sunday) and see if the are the same ones.
I guess my next step would be the fuel injector? Anyone else dealt with this issue and has some insight to what could be going on?
Also just so I make sure I did things right, can someone remind me the cylinder layout of the 5.4 V8? Was I correct in thinking that the odds are on the passenger side and evens on the driver side? With numbers one and two towards the front of the engine (so #3 would have been the second one back on the passenger side)?
Thanks.

You have to have the code cleared to turn the CEL offWill have my friend check the codes again tomorrow (Sunday) and see if the are the same ones.

You can research Ebay feedback and this site and make a decision from there.
Good luck and let us know how it works out for you.

TJK, Thanks for the numbering.
Hmmm.. Well from that layout it looks I replaced the wrong COP. Looks like I replaced #2.
Had my friend check the codes again today and was getting the same codes. Probably wont have time until next weekend to work on it.
I saw from doing a little bit of research on the term "misfire" a few of the threads with those links to the ebay sites. Ill see if I can get #3 working again and then probably this spring buy the set and replace them all.
Thanks for the replies.
