Engine stumbles around 4500 rpm - new distributor cap, rotor, wires

<< < (2/5) > >>

chukT:
With what you had done, I would also suspect the base timing first. Verify that it is set properly as your next step.

94daves:
I'm back at it again to fix this problem.  Timing has been checked and verified by the shop that did the work in 2018 before I put it away for the winter.  There are no codes, no check engine light.  Does anyone have any ideas what could be causing this misfire/stumble at 4500 rpm?

Rocketman:
I wonder if your new distributor is faulty. Is it new/used/rebuilt? Do you still have the old one? What was the reason for replacing?

I saw a Capri distributor with bad internal bearings cause a miss in the past. The shaft was bouncing around and would not give a reliable signal to the pickup coil at higher RPM

94daves:
Actually I only replaced the cap and rotor, not the distributor itself. 

94daves:
I'm back at it again!  I still have the same stumble around 4,500-5,000 rpm.  Could it be bad wires or bad spark plugs?  If the wires were attached in the wrong order on the distributor, would I notice a stumble at lower RPM, too?
