Giving My Car Some Tlc

[mcwatson]

My car is an IS200 Sport 51 plate and just knocking on the door of 90k miles. I've had it from new (month short of 6 years) and have loved the car all the way through.

Was recently thinking of changing it but instead spent some time and cash giving it some TLC and sorting a few problems. Last week, had new tyres all round, full geometry by the Doctor and new brake discs and pads. Been thoroughly cleaned inside and out and its almost like brand new.

There are just a couple more things I need to do to complete the job and thats where my questions come in!!

1) I think my fuel consumption has deteriated a bit so wanted to know if there is such a thing as an engine tune up possible on these cars or are engines of today only able to be plugged into a computer. Or do they adjust themselves for optimal running. If a computer is required, is it only a main dealer than can ensure the engine is running well? If not, where else?

2) Now I've had my geometry done, everything now feels solid except for the gearbox. Its starting to feel a little clunky but would expect this after 90k miles. Its not in need of replacement (I hope) but wanted to know if a change of the gearbox oil would make a difference and make the changing of gear more fluid and solid?

As the car is now 6 years old and 90k miles, I'm probably going to use a local mechanic as opposed to dealer for service as just can't justify the costs!!

Looking forward to hearing anyone's answers to my questions!!

I would say book it in and have a service and change gearbox/diff oil, plugs and filters.
