My wife has noticed and I have verified that sometimes, meaning not every time, when you turn the left turn signal it will blink double time and then other times it blinks regular. any suggestions :?

Sounds like a flasher relay going bad.

I would take a close look at the turn signal lamps (left side front & rear) and their respective sockets. Turn signals blinking at double speed is symptomatic of one of the turn signal lamps being burned out. (open ckt.) Realizing that your particular problem is intermittent may point to a fault with a socket or wiring harness or corrosion.
