Hey folks!hoping someone out there is familiar with this problem. I swapped out the cfi on my 85, and now it starts and idles just fine but whenever i pick up the throttle to(i'm guessing here)2500rpm the engine starts misfiring and idles very rough. when i kill the ignition and then restart it, it idles fine again. I swapped distributors and have installed the duraspark II control box. i'm stumped? have wired and rewired with the hayes manuel till i'm blue in the face
