im at 3000 rpms around 70 mph and when i let off the gas it jumps? i have no clue what it is like it hickups? or misses any idea guys? i have changed the coil pak to the msd and msd wires should i put the stock coil back on and see if it does it? or is it something else? any help?? thanks rob

 

I don't know if it is the msd coil pack or not. I just took my msd coil off today and put my stock one back on and it seems to run smoother but, I didn't have the problem that you are experiencing.

 

thanks littleone231 i just got done taking mine off too. the wires and coil. not changing the plugs yet. ill drive it tomorrow and see. if not i will change the plugs back to the platuims.. anybody else not happy with there msd coil?

 

I did leave my wires on becuase with 63,000 on them I figured they were getting worn down.
