    Misfire on cylinder 4 could be as simple as needing a new spark plug, otherwise could be the coil pack on its way out.

    have you not got anybody local with tech2 or opcom? you could do with finding out what the fuel pressure is using the live data and seeing if the desired and actual are roughly the same after half hour of idling

    this field remedy may be of some use to you or somebody with the right equipment

    Signum/Vectra 2003 To 2005 - Engine Type: Z22YH

    High Pressure Pump, Fuel Pressure Regulator - Defective (P1191 set)

    The customer complains that the MIL is on. P1191 us set in the ECU.

    1. High pressure pump defective, vehicle not driveable

    2. Fuel pressure regulator defective, vehicle runs in emergency operating mode

    This is caused by a defective high pressure pump or fuel pressure regulator valve. In case of customer complaint proceed as follows to verify the defective part:

    1. Check fuel feed pressure at high-pressure pump with manometer (engine running)

    Is primary feed pressure less than 3, 4 bar?

    Yes: Low pressure fuel feed failure -> check fuse, relay, intank module.

    2. Measure fuel pressure in the high pressure rail at idle by using Tech2 Datalist.

    Is fuel pressure in the high pressure rail less than 600kPa?

    Yes: High pressure pump defect, replace.

    3. Pull off connector (two-core) of the fuel pressure regulator.

    Measure the voltage of the fuel pressure sensor at 3000RPM (standing vehicle) with Tech2.

    Is Voltage greater than 1, 2V?

    Yes: Fuel pressure regulator defect, replace.

    4. Defect is not clearly allocable to one component. Proceed according to TIS 2000 service instruction.

    TIS Reference Number: E0001614
