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)?
