[speedy]

hi guys... after changing the plugs and wires I am having rough idle issues. I am curious why factory steel braided wires are grounded and the magnacor ones are not?
anyway after reading other posts I found out by using a timing light and hooking it up to each wire I could find out which one is not working.
I discovered that #4 is not working but all others were. I thought if I messed up wire connectors to dist then two would not work. I put old plugs and wires back on and same results. I know from bentley manual the notch on on dist where number 1 is but I have double checked all wires are in the right places. what am I doing wrong????
