car has 39k on it and its been sitting for 9 yrs. stars and idles no problem when put in gear runs shifts and as your building up speed it starts to bog down like it went from 3rd gear to 6th gear to describe what I'm saying. I can put pedal to the floor and car will kick down and get back in gear so to say and go , but once its up there it will go shift back to a bogging down feeling. my tach is not reading right either. I'm not the mechanic so to say so can anyone help ? thanks
