On way to work at stop sign and stop light, I noticed the tachometer "bobble" a little at idle. It has had ever so so slight done that since I got it in 2014 and stealership said it was normal. It was a little more than that this time I thought but it went away and no light came on. After work, I remote started it and it was not running when I came out. Started it & the check engine light came on blinking and it had turned off the stability track and traction control plus running like it was missing. I put my OBDII reader in and pulled up TorquePro to see the code which it stated cylinder 7 misfire (P0307). Truck has 227k miles on it.
1. Assuming I need to replace plug wires and plugs? (OEM original I hate to say)
2. Also assuming from research ACDelco 748UU and ACDelco 41-110 plugs are way to go?
3. Assuming I don't need to replace the coils, correct?
Thanks in advance for the advice.
