    Not firing on 1 & 2. Compression is 150 and 145. Tested the spark w an in-line spark checker and both have juice. Checked the plug gap. Spark plugs are new.
    Where from here? Thanks

    63 s3 stock motor 32/34 Weber Pertronix Lucas coil. Running rough so replaced cap rotor wires and plugs. Still runs like crap. Pull the wires on 1 then 2 - runs the same. Thanks

    Compression, fuel and spark at the right time usually makes things go bang. Any chance that you swapped the plug wires for #1 and #2 cylinders?

    Look for vacuum leak on intake runners or plumbing that only serves affected cylinders, Shannon
