Yes, I'm talking about my '85. I eliminated every other ignition component and finally decided to check out the ICU. I took it to a Volvo mechanic and he immediately said "That box is your problem." He said that he'd had nothing but problems with them and sold me a used Volvo unit for $100. I plugged it in and haven't had a problem since.
I only suggested the ICU if there was an aftermarket one in. I'm pretty sure Programma makes ICUs, not reconditions used ones, as it looked much different from a Volvo unit. New Volvo units list for like $400 or something like that, so I wasn't about to spend that on a $200 car.
Other than my '89 which I owned for only a year before wrecking it at age 17, all my experience is with '85 and older 240s. I am out of my element on this thread, apparently, and retract my diagnosis.
Sorry for the bad advice.
Charlie
