It's all part of the game. After my MS, Fuel Rail, Fuel lines, and thermostat, replacement, I had a coolant leak from the thermostat gasket, two fuel leaks from the AN fittings, one relay had two ground wires instead of a hot and a ground.....but after that was all fixed, it was smooth sailing. Even the pros need to shakedown their cars before they hit the track, so I dont feel so bad.
