Review on 🔥 ENA Set of 2 Ignition Coil Pack Compatible with Cadillac Pontiac DeVille SRX STS XLR 2004-2006 Bonneville 4.6L V8 C1509 UF-372 Replacement: High Quality Ignition Coils for Cadillac and Pontiac Models by Dave Giri

I drove about 200 miles and had handling issues, the car ran horribly and after the engine warmed up everything stabilized. Since I replaced all the ignition coils, I unfortunately assumed that it wasn't the cause and started the diagnosis, invested a lot of time and found nothing. I still had my old coils so I replaced the front four rear with the factory rail because the replacement uses different terminals on the coil, then I replaced the rear coil where I was having the misfires. Didn't solve my problem, ended up removing the entire back rail and found the problem was a bad connector, only three of the four pins were visible. I contacted the seller for a warranty exchange but received no response.
