First of all, the "sluggishness" you feel is the difference in the gear ratios. SR5's typically have 3.90's. Limited's have 4.10's. There's a big difference when pushing 265/70-16's and MUCH more of a difference when you go to 285/75-16.

My guess on the rough idle is either a loose plug wire or a dirty MAF sensor and Throttle Body.

 

Thanks Andy... I knew it had to do something w/the gear ratio! As for the idle it was a dirty air flow sensor. My CEL came on and the code showed it was my Air flow sensor. Thanks for the help everyo ne!!
