Default rpm not smooth, kinda jumpy
on my 1994 cobra the rpms arent smooth when im 100% on the throttle. It happens when i get around 4700+ RPMS. what could cause this? The distributer cap and rotor are new, the plugs only have 3,000 miles on them; along with the wires. Could this be a mass air flow sensor?

The Maf is the mass air flow sensor right?

Define not smooth? Does the RPM shoot up? If it does that could be the clutch slipping when you start making a lot of power at that RPM.
