Hello my friends! It has been many years since I have posted. I have an '04 Lightning that just turned 90,000 miles. She is bone stock. I have noticed lately that when I hammer it, I detect a slight vibration in my foot from the gas pedal. Very strange. Still runs & performs fine. Just feels that something may be going on with this strange vibration. Again, only when I get on it, not even full throttle. Looking forward to your replies.
