I have a 1993 ford f150 4x4 I had a really bad misfire.. I found out that the misfire was a bad spark plug so I replaced all my spark plugs and wires and the problem is was better but I still have a slight misfire...what can I do to fix this

 

Timing? Cap & rotor, injectors, crossed plug wires,running rich or lean. It could be a number of things. Pull codes and vac.

 

I pulled my codes and got code 626

 

i think that is some transmission code? do you know what that code means and what i should check for that?

 

my cap and rotor need replaced so I will be replacing that soon
