misfire so i have changed the optispark,plugs,and alternator do to low voltage output. but yet i still have a mis only at light throttle as soon as you start laying into it it goes away. just only when cruising or not accelerating. does anyone have any ideas what this could be? also ran a vacuum test and it has plenty of vacuum so im not thinking vacuum leak

im having the same problem but i also have a high idle. (1200rpm) after an ac delco opti replacement at first i thought maybe the opti wasnt alighned properly but mines a 97 no splined gear. ive seen in other threads were people put them in off a tooth and the timings off. just a thought
does yours idle high?

no ses lights. and havnt checked fuel pressure. if you dont align the teeth right it doesnt sit flat across the face of the timing cover so i didnt do that. im wondering if im running to cold of a plug? i dont know to much about all that. the plugs that im running were recommended to me.
