I’ve got a 94 gt 5.0 that runs great most the time. Lately tho it’s started cutting out around 3500rpm. While accelerating it’ll hit 3500rpm then sound like 2 step and no longer accelerates until I let off or it shifts. Any ideas on why it would do this? Only time I’ve seen it before is when I got water in the air filter but the air filter is dry and there’s no moisture in the intake
