    Check the cylinder compression; if it is less than 160 psi in any cylinder; the engine will have to be repaired mechanically before it can run right. This may just involve having the head rebuilt; or it could require a new or remanufactured motor.

    Dirty or unsuitable spark plugs, a bad ignition coil, bad plug wires, or a dirty or cracked distributor cap or rotor will also cause this. NGK plugs do not run well in this motor. Autolite #63, or Champion RN11YC or RN11YC4 are the best choices. Plug gap should be .040" (1.0 mm).
    Improperly adjusted ignition timing (from not first disabling the electronic spark timing circuit before setting or checking timing) will also do this.
    The fuel filter is located underneath the car, on the driver's side, in front of the fuel tank. It is shielded by a metal cover, held on by 2 bolts. I usually remove the left rear wheel to access the filter.
