Hi. i have a 2000 taur with the vulcan ffv. 66,xxx miles. Lately Ive been noticing a slight vibration under hard acceleration. Its nothing violent, but this is the first time its done it. the car is due for an oil change in about 1000 miles, and a trans flush in about 3000 miles. Any ideas? Actually, this has only happened after i did the strut locator tab mod and lowered the front more. Help me out folks! Thanks a mill.
