Wez928

This post is in addition to the brakes and turn signals post. 83 928S. The engine is also down on power. It has 55000 actual miles,and has been sitting for 2 1\2 years. I.ve added fuel injector cleaner and new plugs but have only drove it for 30 -40 miles, because of the brakelights. It seems to be misfiring at idle and lags at WOT from a dead start. Engine runs smooth at highway speeds. I put a test light on the + side of the coil and it barely would light up with ign. on. Is this because of a resistor on the ignition or could it be a ground? Thanks for any replys.:]
