I just put a new set in my 03, when i took it out for a test drive I had a miss, codes showed the cyl 8 contribution and balance. When I plugged the inj harness into the inj plug in the head and pushed in the C spring/clip to lock it together, I missed the groove and it pushed the connection just far enough apart to break connection. Replugged and was fine. Yours could have worked loose. Sometimes inj dont last very long, mine has had numerous inj in 196,000 mi some only lasted 30,000 mi.

This.

I was getting a contribution code for number 3. It only showed when I was wot, changed fuel spring and code has not returned. I don't have a fuel pressure gauge but it could very possibly be that.
