Ok, rest assured all federal parts are intact and in place. But more questions...
So the high idle was the map was plugged into the wrong port on the tb. So idle is fine. Still having hesitation on a constant speed, but no other time. I adjusted the tps, iac/tb/intake were all cleaned during the motor teardown/rebuild. And also, I'm smelling a gas like smell, not horrible, but present, almost like an old push mower, it has exhaust smell, but a hint of unburnt fuel. I'm leaning towards maybe the fuel pressure regulator. At least, that's what my searches pulled as a popular culprit. Ideas?
