every time i try to upgrade the ignition coil it misfires... i put the stock one back in it its gone... it does this with all brands.. i tried summit,MSD, and accels... and i cant figure out why it misfires with higher voltage ignition coils...

 

have u tried checking ur wiring for the spark plugs?

 

yea i have checked everything...even changed the cap rotor,new plugs,and wires.. and still does the same things... i would just keep the stock one but they would not give me my money back for the ignition coil just trade.. so i might aswell fix the problem i got and use the coil...

a what plug wires are on car and how old?

 

i got summit wires they are about a 2 months old, and before the summit wires i had MSD wires and did the same problem..

 

why in the world did you pull the MSD ones they are low resist and give more power to the plug....what is your plug gap? and what coil are you using?

 

the msd ones where old and riped.. i thought that was the problem but it was not.. the gap is set at 50-52.... right now the stock one is on there.. it only misfires with high voltage coils..

 

TTT...

 

What Module are you using?
