    12 faults coming up at once not sure what to do.

    hi there, could anybody help. took astra 1.6 8v 2001 to auto electrican
    because engine management light is stuck on.
    he tested it and 12 faults have come up,the car running fine apart from cutting out when engine is cold only happens when i go on the motorway for about 8miles then come off but once the engine warms up, the car is fine.
    temp gauge is not working properly as well,also had it to my local garage he is not sure he seems to think it could be the wires running to the temp sensor on the block at the side.every time he moved the wires he was getting a different reading so he said take it to a auto electrican and he is not sure.
    the faults that are coming up are

    po105 manifold absolute pressure sensor circuit voltage low

    po1550 electronic throttle contol limp home,forced engine stop

    p1230 main relay stuck open

    p1120 acceleration pedal position sensor 1 low input

    p1122 acceleration pedal position sensor 2 voltage high

    p1122 acceleration pedal position sensor 2 voltage low

    p1550 electronic throttle control limp home,power management

    p0220 throttle position sensor circuit 2 voltage low

    p0120 throttle position sensor circuit 1 voltage high

    p1550 electronic throttle control limp home,limited performance

    p0105 manifold absolute pressure sensor circuit voltage low

    these are the faults that came up yesterday but the car is running fine apart fron it trying to cut out when cold.
    if anybody could help please get in touch just very puzzled with the amount of faults coming at once not sure what to do next.

    thanks.

    Welcome mate

    First thing i'd do is get all the fault codes reset as alot of them could be old ones then when it comes on again get the codes read again to see whats on
