car is missing really bad only when it warms up and i hooked up my lap top and used freescan to see if it was knocking and no knock readings while it misses. the car sat for 4 days and my plugs were gapped to .035 and i am just a boltons car for now ... but i had plans of spraying soon. A dead nitrous noid stopped that for a while ... i just installed a vig 3200 and went for a test drive every thing is all good there but now i have a bad mis that was not there before the swap and the car seems to idle just fine till i give it gas

WTF ...?

i took it out last night and looked for any arcing (checking for bad wires), and there was none while the car was missing. so i am going to change plugs tomorrow and gap them to .055 and hope for the best ...

the opti is the stocker i think and maybe has a 110000 miles on it if it is stock. the first LT1 had a spun rod so i just did a whole motor swap and opti included.

free scan also shows no codes when the mis is going on ... ?

What plugs are u using? And they should be gapped at .050 i believe...i may be wrong but y are going to gain alot of power back by gapping them properly. U could just have a bad plug. If u have an infared temp gun point it at each exhaust cylinder and u can find which one is not firing by the low temp. Thats how i do it...saves alot of guess work and time. Just my .02 hope it helps.

Was the car retuned for the convertor install? Double check the plug wires, make sure they are on the right plugs.
