Sluggish Accleration

[mmuthubanda]

I have a 2000 ES300 with 82000KM. Recently I have noticed a sluggishness in the accleration between 40 - 60 KMPH. The car runs fine afterwards at higher speeds.

Also there is a slight vibration of the gas pedals during this sluggish period.

I took it to the dealer and they say it could be the front pipe.

I need some info on this if someone else had the same simptoms.

Can you give us some of the maintenance history on the car?

[mmuthubanda]

The car has been maintained by Lexus dealer for all regular services.

I never had any other problem with the car.

I do not feel the sluggishness on the highway.

Only at speeds 40 - 60 KMPH I feel the uneasyness.

This just started about 1000 KM ago.

Perhaps start with the obvious. 82,000kms is slightly under the average km's a 5 year old car normally as. Perhaps over the years the car has had many 'short trips' & items such as the spark plugs are a bit fouled from (even though they say you can go over 160,000 kms!) not reaching operating temperature or the fuel injectors are gummed up. I got my 01 ES with 72,000 kms but had the Lexus dealer do a complete 'major' tune up on the car before I took delivery with records (and they returned the old spark plugs back to me as well) to prove. Perhaps something simple my do wonders for the sluggish performance of the car. Just my 2 cents B) Keep us posted
