It seems like the only plausible thing left is the SMEC, but that is an odd way to fail, only firing 1/4 the time. It doesn't have different circuitry for firing different cylinders does it? It does have separate injector drivers, or at least 2 to fire in pairs. It lets the distributor do the work to pick the cylinder.
Are you using the factory style cap where the wires are the contacts for the rotor? One other thing, swap the plug wires around on the cap and see if the working cylinder follows the wire or stays on the #3 post. Did you double check that they are inserted in correctly since they make up the rotor contacts like Neil suggests? ----- Original Message ----- From: "Neil Emiro" <[email protected]> To: <[email protected]>; <[email protected]> Sent: Friday, October 23, 2009 5:20 PM Subject: Re: SD> odd problem, running on 1 cyl, 88 Shelby Z > It could be the SMEC, certainly.
