Hey I got the coil you guys recommended installed and it has the proper voltage, same misfire though.
Its weird, sometimes when I rev it up quickly (like a hard acceleration) its fine, nice and smooth all the way up with tons of power.
Then other times it pops out of the tailpipe and has a noticeable loss of power while thats happening. Completely random when it happens, might run good once, then 3 seconds later on the next acceleration it misfires, could do that a few times or run good again the next time.
I uploaded a .zip file on here of an mp3 I made with the popping sound if it helps anyone to figure out. I am at a loss on this one. Nothing seems to be able to fix it.
Heres what I have done:
rebuilt carb (edelbrock 750cfm manual choke)
new intake manifold gaskets
new spark plugs (acdelco r45ts if I remember correctly)
new MSD blaster MSD-8222
new spark plug wires
I did each of those 1 at a time to see if that fixed it or not and none of it did.
