I am new to the forum and am looking for some help. I just picked up a Everett Morrison 1967 Cobra replica that has a Ford 390 FE in it. It sounds like it is not running on all cylinders so I took off the plug wires one by one off the distributor cap and on cylinders 1, 4, 6 & 7 it did not make any difference if the plug wire was removed or attached. This does not seem right, as when I remove the other plug wires the motor bogs down as I would figure. I tested to see if I was getting spark at the end of each of the plug wires and swapped in new plugs but nothing is changing. Any suggestions on what is going on or what I can try next? Thank you so much
If you replaced the plugs and wires and cap and rotor and you still have the problem, try removing the valve covers and with the engine running watch the rocker arms, if they are bearly moving on the cylines you mentioned, you might need a new cam.
Thanks KDTRUCKER, I have not replaced the Cap & Rotor as of yet, they are new, so would you recommend that I do that first or take the valve covers off first? Thank you again, I do appreicate your time.
