Measure the throttle bores and plates and post those on here so maybe SOMEONE can look them up in Holley on line spec charts work scope up



I agree on what it looks like.

What ignition system? Sounds like when an ecu has a bad ground. Gets worse when hot. Something like a petronix will get wonky when it’s hot wire sees lower voltage when under hood temps go up. Looks like you don’t have a voltage reg hooked up. Running a one wire? Is it charging good at low rpm?

I want my fair share
