2001 corolla 3 sp auto, 67k miles. Just aquired so have no performance history. Have poor cold start (75-80 Deg F) acceleration from zero to 20-25 mph with better, but what I feel is less than expected when warmed up also. actually accelerates from 20-45 better that 0-25. VVT-i, auto trans, fuel injection, computer??? HELP

Almost sounds like the engine is plugged up. Did you check the air filter?

your first gear is going out in your transmission get it checked

Not plugged. Revs well and pulls strong at intermediate to higher revs. Performs like a 75 hp a low RPM and like the 120 HP that it is at higher revs.

Not the trans. Cleanly and solidly upshifts and down shifts in and out of 1st. Now has 75K and seems to be performing slightly better. Learning to keep foot into it enough to keep it from upshifting without going to WOT helps. Although this isn't consistant with other Fuel injection cars, it is what it is. I did a dump of the computer for errors and found none.

sounds like a 3 spd to me..man i hate the way they are geared.

hii,
I have a poor acceleration too at my 2001 corolla, after a garage check, by connection a computer to the car and a ride, he told me that the air sensor is dirty,
after a clean of the sensor the car is accelerate excellent again.
