Sounds familiar. Check alternator output and connections between the
alternator and ignition coil, notably the big junction block on the
inner fender that the 8-gauge main power feeder from the alternator
attached to.

Subject: [alfa] My GTV-6 has developed a "miss"
Has anyone here seen this before:
The car started to miss, under load at around 5 grand. At first, it
was just a slight stumble under load. as long as I didn't push it, it
ran fine. It has been getting worse. Now it runs rough at low RPM and
idle, smoothes out between two and four grand, and starts to break-up
again above that. I checked the ignition by using an ohm meter on the
ignition coil and the DC resistance is in the middle of the range
called out by the shop manual. I tried pulling each spark plug lead
individually to see if the engine got worse or remained the same. Each
pulled wire made the car run worse, so it's not a bad plug or
something that could be attributed to any one cylinder. I checked the
distributor and the rotor and they seem fine. Any ideas?
