Just got around to servicing my IS200. 118000 on the clock & I can't believe the difference the service made ! Car was running fine but after the service the crunch between 1st & 2nd gear is gone 😄. Because I don't know what the previous owner had done I fitted a new set of NGK plugs & it seems to have made a difference to the pick up. The only thing I couldn't do was the diff oil because whoever was last at it rounded the filler bolt. I wasn't comfortable trying to remove the filler bolt with the car on axel stands in my garden so I've booked the car into the local workshop for them to put it up on the ramp and do it. Finding myself looking for reasons to go driving & taking the long way 😉
