hi every one , im new to this site . from what I have been reading this the place to be . I just got my first Camaro this summer and it is 93 z28 I got really cheap from a friend of mine . i could use some help if there is any one who can help me. now i am having a problems with the ignition it has the opti spark system and it is no fun by any means . it runs fine for 40 min then it has a miss and pops through the exhaust no power falls on it face when you give it more gas . i m not really shure if the opti spark is even the problem , any help would be great , thank you
