You are in the Lexus GS

I have a 1991 Nissan Maxima SP with 108,000 miles and have never changed the transmission fluid, it runs great. I also have a Lexus 1999 GS300 with 65,000 miles, and trying to decide whether I should change T.F.
I have read in a past article that said original T.F. should not be changed. I have followed the Lexus manual and did the timing belt, drive belt, water pump etc., but I'm hesitant on the T.F., any thoughts.
Another problem... occasional surge when pressing gas pedal. I have owned this car for 10 years and have avoided any mishaps, however while having the car in for some work at a Firestone shop one of the mechanics caused the car to surge and hit the side of the building causing major damage which they paid for.
Did or does anyone have a similar problem.

Hello. I am looking to buy a 2001 lexus gs 300 with 94k miles on it. Seems to be in good condition. the 2nd owner has only owned the car since Feb. Any ideas at what types of maintenance this car will be needing in the near future? timing belt, water pump? assuming it checks out ok, is $8500 a good price? person to person kelley blue book is $7950 but no sure if a lexus in good condition goes by KBB. any insight would be greatly appreciated.

2001 GS300 with 75K should be about $7500, but for a good-condition car $8500 is OK.
Have not had any problems with mine except replacing O2 sensor and Mass airflow sensor.

A/C starts to smell rotten 5 minutes after turn on.
This is terrible.
anyone knows the fix?

The GS300 engine is a high-compression engine requiring 91 octane gas. Use lower octane will likely cause premature ignition, incomplete burning of fuel, causing engine knocking, reducing horse power and fuel efficiency.
Incomplete fuel burn will produce more pollutants, eventually fouling oxygen sensors and catalytic converter, which would be expensive to replace.
If the engine can run reliably on cheaper low octane fuels, the engineers would have stated so in the manuals.

The engine control computer automatically retards the ignition timing to compensate for lower octane fuel. Therefore this will protect the engine from damage! That's the reason that Lexus vehicles incorporated this feature in the programing of the computer.
