i dont know what is going on with my z28 but it has been bogging really badly. seems like worst when shifting form first to second. its an automatic and seems like it just falls on it face. it also seems like when im on the fuel and accelerating that it will pause and then regain power then pause again but i know i am not moving my foot at all. i want to fix this because i know that this thing can preform way better than it is right now. its a 1999 z28 stock its my daily driver and im looking to get it sold by the end of the summer but i want the next buyer to be happy with what it can offer and i want to fix it before trying to sell.... let me know if anyone else is having problems or if you have any ideas.
