Misses intermittently when accelerating, surges when idling, occasionally dies@ red lights & stop signs. 1/12-new timing belt, dist. cap, rotor button; 7/12-replaced fuel filter; 8/12-new plugs & wires, replaced reversed, broken crank gear, reset timing & tune-up to fact. specs, repaired bad injector connection; 11/12-ran Seafoam thru engine; 12/12-cleaned & adjusted throttle body & tried different mass air meter, repaired both tailgate wiring harnesses, repaired engine wiring harness, tried different ignition computer. Car in shop now to try fuel relay switch/valve. The only thing all this has done thus far is to essentially stop the ignition/engine spark or clatter. Including tires, I spent over $3,000. in 2012 on a car I bought new in'84 that's not worth half that. Other than selling it for scrap, any hope or help out there for me?
