I have a 95 Grand Prix GTP, and if I'm signalling at idle (in gear, my foot on the brakeat a dead stop) my RPM decreases by about 50 RPM when the signal light is lit and cycles back up when it turns off and continues during the periodicity of the signalling. My dash lights also slightly dim with the same trend. My question is, is this normal? Should the engine idle and interior accessory lights really be this sensitive to such a small electrical draw? I have checked my battery at idle and it's charging at 13.8V, and I haven't had any other electrical problems. However, I do have some other erratic idling when not signalling, so if this could all be attributed to the same electrical problem I'd love to figure it out. Thanks.
