Hard miss at ~3800RPM ?????
I'm stumped over this one so I could use some help brainstorming the issue. It's an 383 LT1 '95z28, vortech s-trim, aftercooler, delteq ignition. Car pulls hard to about 3800rpm, stumbles like it misses all 8 and then pulls hard to redline. Any ideas about what could cause this? a/f ratios are good.
