my engine was bored .030 but i kept the 8-1 compression, will i have to gap my plugs differently or will they stay the same.my car idles fine but still dies if i throttle it and let off completely then it is a bitch to start after.if i throttle it and bring it down slowly it will idle rough for a min then clean up .any ideas what this problem is

Plug gaps would be the same as usual around .030-.032".

Clean out your IAC and check your TPS voltage closed and a even voltage rise when opening. (Check the Tech section / FAQ's).
