    My SV6 is now two years old, and just past 60,000 Km.

    We have just come home from ten days in sunny (???) QLD. I had the 60K service just before we left, and received a call during the day "recommending" a fuel injector service and throttle body clean, at about $200. I knocked it back.

    Since getting the SV6, I have done this trip three times, at about 1,500 Km, about 30,000 Km and now 60,000 Km. Fuel consumption first time was about 8.0 L/100Km and 7.8L/100Km at 30,000 Km. Both those trips averaged 90Km/Hr. This time it was 7.6L/100Km with an everage speed of 93 Km/Hr.

    The only change in the car has been replacing the original Bridgestone tyres with Goodyear LS2's.

    I just wonder if and when a fuel injector service and throttle body clean might be advisable? It certainly is not needed yet.

    I got offered the same thing recently during my 30000km service, does make you wonder when they actually do need it?

    Throttle body clean: Rip the intake off the throttle body and have a look inside, if its all black in there it needs a clean out.

    Injector Service hard to say really. If the cars running sweet and fuel economy is good then I wouldnt bother. Having said that I do my own car every now and then just as general maintenance.

    DONT spray anything into the throttle body, spray it onto the rag then clean with the rag.

    Old mechanical throttles are fine but not the electronic ones.

    Been lucky I guess, electrical sensors/components dont like throttle body cleaner/degreaser too much.

    wouldn't the electrical motor that operates the throttle body be sealed from the actual throttle body? otherwise it would be a vacume leak? idle issues etc? degreaser is no nastier then petrol or oil that these things are designed to operate with.

    Thats the thing, the cleaner can eat away the seals.

    Trust me Ive seen it happen, most of the time you will get away with it but do you want to take the risk?

    Tyres can make alot of difference on fuel economy, I would'nt worry about an injector clean it's just a way for the dealers to make money especially at 60k it's only just run in.

    Throttle clean and injector clean is a money spinner for the dealers...
    If the cars needed this servicing Holden would have scheduled it!

    Not always, we've had cars in that have thrown TPS codes because the throttle plate isnt returning home properly, turns out the throttle body was so carboned up the plate couldnt close. This can cause rough idle etc. Theres plenty of items that could be made part of the service, problem is service costs are high enough already so they become optional extras. They become a problem eventually if not done when recommended.
