Hi i have a 2004 se 2.7 and cylider 6 is not firing gives me a p0356. at first i thought maybe its just a bad coil. so i swap coils with cylinder 4 hoping cylinder 4 wont fire and its just a coil... i was wrong cylinder 6 still not firing... i replace the plug and still no firing. I removed coil (still connected) to see if its getting spark and no spark... im stumped it recently had a computer swap since the computer died on me when i got the replacement it didnt start since they sent me a computer with a skim key. my car did not have a skim key so i sent it back and they gave me one without the skim key and now it starts but cylinder 6 wont start. it ran just fine before it sat for a month.any help???
