sluggish performance
 

i dont get it my car was runnin fine a couple days ago and i have notieced now that all of sudden the performance has really droped out of nowhere. the auto transmission is sluggish big time. i can barely accelerate feels like i am carrying a 500 pound load in the back.i was getting 0-60 5.3 now im hitting like 5.9-6.0 wtf like out of nowhere the car just dropped horsepower i dont get it. it has 45,000 miles on it you guys think it need a tune up?

Anyone??????

did you buy the car used? have you changed the air filter? what year is it? give as much info as you can.

yeah dude... gotta make with the info... look at your oil, tell us what sounds the car is making (new ones), anything but a 0-60 time change? more info = more suggestions.
