Is there something I need to un hook to adjust the timing on my 91 5.0? Usualy there is one wire that needs to be unhooked but I havn't found one. The book talks about a vacuum line for some, that's not me. It talks about a single wire that hooks up right above the rest of the wires on the distributor, I don't have that either. Is there something I need to unhook? Car still doesn't feal right and the way it sits with out unhooking anything it has about 14 degrees of timing. Seeing another post on the forum has me thinking.
