    Hey all
    I have a VTII Clubsport LS1 auto.
    I'm having trouble with it surging and a substantial loss in power. When its cold its fine but after around half an hour of driving it starts happening. If you put your foot down to less than half it really struggles to get going and surges. Give it WOT and it goes as it should. It has no codes and engine light never comes on. Been searching the forums but can't seem to find what I'm looking for. I have a obd scanner and the 02's volts are flickering as they should so I'm a bit stumped! Have cleaned throttle body and maf aswell
    Any help would be greatly appreciated!

    do you have a lot of glitter handy? I kid, I kid!

    So only when hot, and "surges" or does it bog down then take off?

    could be ya oxy sensors on the tail pipe , one on each side below the firewall, also maybe ya crank angle sensor, or coil breaking down as it gets hot,.. or leads

    Bit of an update. Changed oxygen sensors and has not helped the problem at all
    Have been working away so haven't had much of a chance to muck around with the car. Checked fuel pressure today and it hold 60psi no worries at all.
    Just not sure where to go next! Any suggestions???
    Its just strange how the car will heat up to operating temp in 10 min of driving but it takes 30 to 40 min of driving for it start running like poo..

    what about fuel filter or pump. or is it your alternator regulator spiked to high, its hard to diagnose can cost lots before u get to the problem.

    Does it have the original temp sensors. A mate had the same issue with his 220i. He bought a brand new aftermarket sensor and it did something similar to this. He went and bought a genuine holden temp sensor and the problem went away.

    So the OP hasn't been around since: shadow6ix Last Activity: Feb 2, 2016, so probably its been sorted or sold the vehicle.

    This sound like electrical breakdown after heat soak... so IAT/MAF(dirty)/Coil Pack/Plugs-Leads/TPS(Sticking/faulty), but I'm no mechanic. ;)
