As Royt suggests clean the TB 1st.

If you still have a problem pull the engine codes to see if a stored fault is present.

The airflow meter on the early LS's is a Karmen Vortex type generally very reliable but expensive new ( if you can still get them) However there are normally some S/H on ebay.

Make sure you change the air filter at the correct service intervals and make sure there is no debris in the filter box which could get sucked into the AFM and damage it as they are very sensitive.

ok steve thanks gil

Might be worth cleaning the throttle body first to eliminate it.....

thanks royt will try that thanks

does anyone know please . does an airflow meter affect the performance.why i ask is because my lexus goes better in the good weather. there is a flat spot every now and again.i wastold it was the throttle position sensor but i have replaced this and it still falters. any help appreciated. thanks gil

Sounds like there could be some sort of blockage of a breather pipe,

or maybe spark plugs need a clean/be replaced, or throttle body needs a good clean.

Is the Air Filter dirty ?

hi dj thanks 1 changed the plugs will try the air filter much obliged gil

any advice please my 1990 ls400 is running erratic. when 1 adjusted the air cleaner it seemed to improve the performance .does the air intake affect the smooth running thanks gil

There is pad wear warning but someone may have bypassed it by joining up the wires.

They wear through when the pads wear, putting on the warning light.

Pads are easy to change, similar to most Japanese.

If you haven't done it before, get some one to supervise your work!!

Remember your life and others may depend on them...

thanks for your advice gil

Hi,

The water pump is driven by the cam belt so this means removing the cambelt to fit the pump plus the strip down is the same to get to the water pump.

It is best to replace both the belt and pump at the same time to avoid 2 major projects instead of one.

THANKS FOR UR HELP STEVE GIL
