Review on 🔥 Ignite Your Engine with Delphi GN10311 Ignition Coil: Unleashing Optimum Performance! by Nigel Morris

...change a few bad actors. Eventually the Check Engine light came on with codes P0305 and P0307. I rebooted my system and drove the truck for another week until the check engine light came on again. I've noticed slight misfires while driving this week, but I wanted to try to isolate the problem just to be sure. When the check engine light came back on, it showed P0307 and several random misfires. So I'm dealing with bad gas? I'm not exactly sure, but since I ordered all the replacement spools, I changed them all. Changes very quickly and the truck has more power in the last few days, no thud when pedaling. It seems stronger and I'm trying to figure out if that's why my fuel economy went from 16mpg to 13mpg. Hopefully over time I can get some of those mpg back. So I installed them on May 9th, 2020.
