1986 desmogged 2f. Recently started spark knocking and cutting off while driving. Typically happens @ 2000+ rpm. It won't do it in my driveway, only while I'm driving. I had a tune-up in January (about 1500 miles ago). I was planning on changing the coil w/ igniter, but finding issues getting the igniter. Is it necessary? Is there an easy alternative? Any suggestions on brands?
