I put the stock coils back in, installed new plug wires and swapped in new spark plugs. I'm still getting an intermittent misfire....it feels like a misfire anyways and I keep getting a misfire code. Plus wideband will read rich when it happens. It's wierd cuz it only happens when the engine warms up and the engine has died several times sitting in traffic. I'm about to throw a grenade under the hood and walk away. What could possibly be wrong with my POS??
