Spark Plug Wires, Fuel Filter, Spark Plugs and Valve Cover Gasket Set. After work was done and paid for, check engine light came back on before I pulled away from the shop. Mechanic read code and now it reads Crankshaft Position Sensor. It was end of day, I drove home and returned car to shop next morning for recheck. Mechanic says he put ina new Crankshaft position sensor but the check engine light did no go out so he put the old one back on. He is now saying I need to replace the ECM. Also, car is now leaking coolant so he says I need to replace "o" rings. Coolant was not leaking when I initially deliverred the car nor when I picked it up after the first day. Any suggestions -- could the ECM be bad? I don't know what to do nor what to believe

Up to this point in time, mechanic 1 has only done some maintenance work on the car. Things that would be done from time to time to maintain the car.
Since you have lost trust in this mechanic, I would go to a different place and have them diagnose the codes. If the second place gives you the same recommendation you can decide what to do.
You can tell the second place you are getting a second opinion, or not.
You need to know where the coolant leak is coming from, if it has anything to do with changing the valve cover gaskets, and what the real reason is for the cylinder miss. That could be something fuel related instead of being a faulty computer.
