    Default 2.2 z22yh problem

    Hi guys

    so all was well with my vectra c until the dreaded car with spanner light came on.
    i got a quick judder at 20-30mph an the spanner light comes on
    then safe mode kicks in, my garage has said it the fuel pressure
    regulator, so that was replaced along with new spark plugs...two days later same is happening, can any of you wise men or ladyís shed some light on what could be going on? Fuel pump was replaced about 5k miles ago also, itís a 2006 sri 2.2 petrol
    thanks

    The only problem I had with that engine was the high pressure fuel pump on the side of the engine, not the one by the tank.
    I to was diagnosed with a fuel pressure regulator and it didn’t help until I replaced the high pressure fuel pump.

    Best option would have been to replace both HPFP and regulator. Same code for both so its a guessing game matey...

    Well the plot thickens! Only code it had was a misfire on cylinder 4, the very next day it had a code for misfire in cylinder 1!
    The misfire seems to jump to random cylinders, Coilpack busted maybe? Would a busted coilpack give the orange car spanner
    light?
