Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My 2002 jetta is a great car, but I can't seem to get it passed 70 mph on the free way. I'm worried something is wrong since my spidomiter says it can go up to 120 someone please help it would be much appreciated!

Dodge charger?....................Is it acting 'wierd at 70? what is your tach doin? will it rev higher in lower gears? Is it a smooth lack of power or does it start running rough? Any aftermarket add-ons?
