doesnt mater if i try to beat on it when its cold.... i start the car a few mins b4 i leave, dont think im a complete dumbass, but my car stays cold for a very long time, although everything is functional, even in the hott summer days. i have to floor it just to go, no hard acceleration. now it is picking and choosing when it wants to do it. once i shift thru 1st and 2nd and shift to 3rd the hesitation usually dissapates.
