The coil pack wiring is a common upset but, oddly enough, it's not something which has made its way into my repository of Supra tech info. It has been posted here in the MKIII forum a couple times though. If you find a good thread with solid info on it let me know and I'll copy it into the FAQ section... I'd look for something but I've got company and had to sneak away to get on here for this long.... The wife's just real funny about me not paying her family enough attention.
