Start with all the standard service items and while performing keep an eye peeled for vac line issues, rubbed wires, loose connectors, and so on.

It sounds like it is misfiring on a cylinder.

If standard service checks/repairs such as new plugs and things donít fix it I would move onto things like fuel pressure.

With 35 years of experience, you should be able to troubleshoot it.

I love that punctuation is not being wasted here,....HA HA....

You say the secondary butterflies have been removed ??
Are the secondary shafts still in place ?
Lots of air will get sucked in through the shaft holes if so....that can cause a few pops and bangs....
One would assume the shafts are there, because they need to drive the Seconsary Throttle Position Sensor, which may be seriously out of adjustment. Or, if the shafts are gone, then the STPS will be stuck in one spot, and it will only have an appropriate value for a few % of the throttle range...

Also, is the PAIR valve still in place ? Are the hoses from it to the rocker covers in place ?
