ok guys i dont post on here much so when i do usually very few people take time to read or help but anyways here it goes. i bought a 91 gt 5spd car a few months ago and it has this wierd thing that happens to it when i get on it and shift at like 5500 it just falls on its face. if i let out of it and get back into it its fine. btw its all stock. i havent had time to do much yet but im gonna pull the codes and stuff tomarrow and see what i come up with. if any of you have any ideas please let me know im kinda lost. thanks in advance.
