    a few things here, if you have p4 issues at that mileage it will probably be down to a couple of things either a poor map because there forcing too much air in and not enough fuel or you have put a sports exhaust on or cut the cats out and not had them mapped out and it makes the car run lean

    my suggestion would be to get a pressure test done and if that is ok then you need someone with a tech2 as it gives you live data and will tell you what the sensors are doing and everything

    and i wouldn't let the tank run dry because it might pull all the crap through the fuel filter and there a pain to get to.

    Mine has started playing up on startup.

    Turn the ignition on and it misfires, no needle search or drops just misfires but a blip of the throttle it goes back to normal and runs fine. No smoke, no smell of fuel, no loss of water or oil.

    Thinking (hoping) it might be a spark plug issue. Got a set sitting around so going to swap them out tomorrow and see if it changes anything.

    No cheap anything on my car or bodged cats or anything like that just the best and it treats me like this , can easily fall out with vxrs probably won’t ever buy another if it’s a piston
    I will know tomorrow as dropped car off tonight at garage so will know tomorrow
    Although I drove it the 4 miles to the garage it didn’t feel too bad and behaved
    Could be a crap map as dynotech did it and wasn’t happy from day one and he refused to even look at it the day after the map was done saying it was my car not his map and wouldn’t even put my standard map back on without charging me
    Will never use them for anything again

    Good to hear, hopefully a change in map will sort it out.

    Its always best to have things checked as you did, theres so many people who immediately jump to P4 issues.
