hey i was wondering if any one would know whats up with my 92 LS400 with 79K miles on it

just recently my car would have a problem accelerating and running right when ever i tried to get on the gas, at around 4K to 5K rpms the car would hesitate and not want to accelerate most of the times its done that was when it down shifted and i was in the 45mph range

around town driving it does just fine, and i really dont get on the gas too much, mostly only when im getting on to the highway or passing a car.

any sort of help would be greatly appreciated , the nearest place that can work on Lexus is 400 miles away

Have you dont a tune-up?

Did you change the fuel filter?

How about spraying out your throttle body with cleaner?

Start with the tune-up question and lets go from there.

ii agree. do a seafoam treatment (do a search).

then change the spatrk plugs and wires.
not that i think the seafoam hurts the plugs.
a mechanic i told this too said, if anything,
the seafoam will CLEAN the plugs.

but at 80k, the plugs probably need changing if not
done already. plugs and wires do not cost a lot and
can work wonders.

do the little things before spending for the big things.

and maybe the air filter and the fuel filter, too.
