hey, i got an 1983 chevy c10 305 automatic truck. The problem i've been having is, when I step on the accelerator the truck drive real slow till i hit 35mph (2nd gear). Very clueless to what may be wrong, thanks for the help.

 

Well, the first problem is the gigantic font lol

Second, the 305.

Third, could be a clogged catalytic converter, gummed up carb, trans is slipping it's hard to tell unless you do some testing. Do you know how to read a vacuum gauge?
