Only cheap HEI works

China is a *****!! There are not too many options except to keep swapping stuff out until you find one good one that works for a long time. I use the Accel Super coil, after buying a few from China I finally bought one from the 80s (used on ebay) and that solved all my problems. It's funny how a 30 year old coil works better than a brand new one from China?????:poke::mad::soapbox::BangHead:
