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?
