tach issues and idle

Ok. ive got a 93 3.8 cat. As of 2day, the entire drivetrain has been relaced, crate 3.8, rebuilt tranny, and i finished the rear end swap earlier today. But now i have a few issues. My tach is acting up but i believe its the connector to the coil. Its fine cruising at any speed, but if i give it enough gas to increase speed by about 5 mph, or shift, the tach will peg at nothing, but then i let off the gas, and it will be fine. The yellow wire in the connector will come out of the plug by itself, which i think is a common problem, but it did that before it went to the trans shop, but now after it came out. it starts happening. The other happened after i changed the PS valve cover gasket. it will die immediately after it cranks if i dont give it a little gas. I have checked for vacuum leaks, disconnected wires and all vacuum lines. All good. I used a new upper intake gasket with the swap. It did not have this issue before. Any ideas on the two?
Remember, if the women dont find you handsome, they should at least find you handy.

When all else fails, get a bigger hammer.
