Campbelt was changed at 109k by Lexus, last service was a full one a couple of years ago, (stamped in book .... What happened in between I haven't any paperwork for) so I'm going to change all fluids anyway front lwr caster arms and ball joints, all filters, prob do fuel filter as well, plugs, not sure about ht leads as I think it's coil packs ......... Was thinking about doing the smiffie Soarer engine flush , paraffin and gear oil mix, worked really well on the 1uzfe but this seems a little more complex so might have to think a little deeper on that one !!!, what would you guys use to clean the maff sensor, definitely a more refined car than the Volvo lol , not saying its not fast, just the seat of the pants dyno needs a recalibration .......
