Small Block & Big Block Chevy Specific - think i have opti problems?

My 93 z28 has been sitting all winter. now when i drive it from a dead stand still , when you hit the gas engine boggs and pops through the intake.like the timing is searching . no engine light on and when warm it gets better at cruise.but if you stop and start again it stilldies down and pops.always would light up the tires at stand still.
any clues guys? thanks :bang:

when mine went out i first started noticing it going up hills under a load and it would buck and it kept getting worse.you may just need to go through a tank or 2 of gas with some injector cleaner also.

seems more of a ignition problem than fuel problem.

ok I found the problem it was the optispark cap and rotor burnt out. thanks for the help slow trap.

see my post in the LT1 section. Talk about burt out ;)

yes i seen your post two fast 4 lv .not sure if i want the msd now. like to know your out come from the company.

the one i had was stock and burnt the center contact of the rotor out. ahd the contact on the cap too. couldnt believe it even ran.
