I don't know what tests were performed by your mechanic, but it's possible you need a new computer.
The way to check for a bad computer is to check reference voltages at your sensors. If one/more of your sensors isn't recieving the correct voltage, and it isn't a fault in the wiring harness/connector, then the computer is bad. Also, if the injectors aren't recieving a pulse, or the pulse isn't within spec (no wiring/connector problems), then your computer is bad. Same thing for the other outputs. But you need to measure these circuits and have the specs to compare them to.
