noticed it about a week ago, on the highway at cruising speed when I would go to change lanes and hit the turn signal, my rpms would fluctuate 150-250 rpm. doesnt happen if im off the throttle, doesnt happen if im accelerating, just when maintaining speed.

at first i thought that it was just me giving a touch of gas anytime i hit the turn signal sub consiously, but i tried it with the cruise control on to eliminate that possibility, and as soon as i hit the turn signal, the cruise control turned off. i dont remember that happening in the past.

i really have no idea what would cause this.. im going to try going harness by harness and disconnect, grease and reconnect to see if that helps, but other than that im stumped..

any ideas?
