so my truck, a 90 c1500 with a tbi 350 in it shifts kind of funny. when it goes from 2nd into 3rd, it stays in 3rd for like a second, then goes right into 4th. i'm not sure if maybe the cable that goes into the tbi is adjusted wrong or what, or even how to adjust it,...any advice?

Here is another set of instructions on how to adjust the cable:
