Can someone help me out here??
My car seems SOOO slow in acceration from 80-120 and from 140-160 km
ie from 50-75 mph and from 85-100 mph
I know the car is not fast, but it is even slower than normal times lol

For example, I punch it at 50 and it accerlates really really slow to 60 but then picks it up from 60-75
And if I punch it at 85, it will take FOREVER to get to 100 mph, BUT if I would have to punch the car at 75, then it would accerlate at a decent rate to 100 mph... ( ie. normal accerlation from 120-160 km/h)

So the car sometimes tends to NOT shift to lower gear or the approperiate gear and sometimes it just doesn't accerlate fast even when it goes to the lower gear!!!

oh boy, I have a headache from writing and reading this all at once...

So if any of u guys have encountered similiar problems or know of anyone that has and you got an idea of how to fix it, please feel free to help!

Thanks for your time!

In his profile it says '98 ES300.

Now to the question: The automatic transmission will NOT downshift if the cars speed is so high that it would cause it to go above redline. This safety prevents it from over revving and possibly damaging your engine.
Also, my friend is a State Trooper and he'd like to know where you drive the car at those speeds. heehee

Sorry, the 98 white pearl is my brother's now
I got a 99 Champeigne one

And I drive on the 401 in Ontario.
What else does he like to know?
I only follow traffic flow.
Believe me when I say that the traffic flow today, to London, ONtario, was averaging about 85-95 mph, ie 130-145 km/h
And it wasn't just 2 or 3 cars
More like 7 or 8 of them

But here is the deal:
Even when I floor my car, it will still accerlate VERY slowly. That is even after it downshifts; it will still accerlate slower than usual
I'll change the oil in 1000 km and see if that will make a difference...

Thanks for replies

Perfect explaination. No other reason.

if your rpms are not climbing then i would suggest replacing the fuel filter, but being that your car is newer i doubt you would have this problem so I'd go with the other guy's responses. My 92 was accelerating slow throughout the whole powerband and was fixed after I replaced the fuel filter.

Sounds like your beating the hell out of it...

Iron, let me know where the traffic is flowing at 140 - 160 KM/h on the 401 & I'll see ya on the highway!! (I'm in the east end of Toronto) lol. How many kilometers on your ES & when was the last time you had a major tune up?

Iron Sheik

Check your pm my friend

I am having the same problem with my 94 ES300. What is up with that?

Iron Sheik

Aye!!! I dont got a clue?
I have to change the oil in 500 km or 310 miles....maybe that has something to do with it?
I tested it out yesterday, not high speeds, but just up to 50 mph (80 km) and it seemed fine.
Like I would step on it at 60, and it will accerlate at nice pace to 80 or 90 km/h, quite a bit faster than it did before.
I had one lil problem though. While I was accerlating half throttle, the car seems to PAUSE a lil at 50 mph (80 km/h) at exactly 4000 rpm. I found that odd.
Anyone has any idea?
Other than that, it felt fine when I nailed it at low speeds. WAY better than what I have mentioned in my first post.

Consider getting a complete 100% transmission flush & clean the filter mesh at the same time. Perhaps your not getting the proper line pressure or lubrication if the fluid is old & dirty. Change the tranny pan gasket & make sure you use the correct tranny fluid otherwise you can do more harm than good.

Probably the same places he drives HIS car at those speeds.
