missing after warmed up,slow start 86 mass air 302

[greedygenius]

It runs fine when its cold no miss,pulls as hard as a stockish 302 will,fuel pressure and everything is fine.Once it warms up it sometimes has a slight miss/studder at higher rpms.Sometimes it runs fine when warmed up.It also starts up slow not that it cranks alot but seems like the starter is barley turning fast enough for it to start.any ideas on what it could be?

i had almost the exact same thing happen and on mine and it turned out the distributor bushings was bad and once it got warm it had play and the shaft was moving around causing the timing to go haywire. not saying thats your problem but acts alot like mine but it could be many other things i'd check your timing first

ive had msd on other cars,But ive heard they are junk on fox bodys.I think its either tfi or a battery connection or ground issue.
