I may be in way over my head, but at 58 I either have to learn, or watch. So here I am. This is a new 370" lq4 with all forged internals and 11:1 Wiseco pistons Summit stage 4 N/A cam . LS7 lifters, 823 heads mild port with lighter valves and .660 PAC springs. Trunion upgrade, Trend hardened pushrods, LS9 head gaskets, ARP studs, LS3 factory intake, and still has the factory 25# injectors @ 58 psi with return fuel line. 102 DBC TB. 2000 chevrolet silverado blue/red P01? pcm. I have added a wideband , but cant get it to read other than voltage at the moment. It was idling @ 4.37V (18.74 AFR). My AEM 30-4110 gauge is maxed out at idle, and my headers glow at idle. I think I also have a timing issue at low idle that may be contributing to the glow. Any help would be greatly appreciated.
